Answer: What
Explanation:
Write a C++ function for the following:
Suppose that Account class has a method called withdraw, which will be inherited by Checking and Savings class. The withdraw method will perform according to account type. So, the late bind is needed. Declare the withdraw method in Account class. The method should take a double input as withdraw amount and output true if the withdraw successfully and false if the withdraw unsuccessfully.
Solution :
class Account

}
[tex]$\text{return}$[/tex] false;
}
}
You will write code to manipulate strings using pointers but without using the string handling functions in string.h. Do not include string.h in your code. You will not get any points unless you use pointers throughout both parts.
You will read in two strings from a file cp4in_1.txt at a time (there will be 2n strings, and you will read them until EOF) and then do the following. You alternately take characters from the two strings and string them together and create a new string which you will store in a new string variable. You may assume that each string is no more than 20 characters long (not including the null terminator), but can be far less. You must use pointers. You may store each string in an array, but are not allowed to treat the string as a character array in the sense that you may not have statements like c[i] = a[i], but rather *c *a is allowed. You will not get any points unless you use pointers.

Imagine that you are helping to build a store management system for a fast food restaurant. Given the following lists, write a program that asks the user for a product name. Next, find out if the restaurant sells that item and report the status to the user. Allow the user to continue to inquire about product names until they elect to quit the program.
Answer:
The program in python is as follows:
def checkstatus(food,foodlists):
if food in foodlists:
return "Available"
else:
return "Not Available"
foodlists = ["Burger","Spaghetti","Potato","Lasagna","Chicken"]
for i in range(len(foodlists)):
foodlists[i] = foodlists[i]. lower()
food = input("Food (Q to quit): ").lower()
while food != "q":
print("Status: ",checkstatus(food,foodlists))
food = input("Food (Q to quit): ").lower()
Explanation:
The program uses function.
The function is defines here. It accepts as input, a food item and a food list
def checkstatus(food,foodlists):
This check if the food is in the food lists
if food in foodlists:
Returns available, if true
return "Available"
Returns Not available, if otherwise
else:
return "Not Available"
The main begins here.
The food list is not given in the question. So, I assumed the following list
foodlists = ["Burger","Spaghetti","Potato","Lasagna","Chicken"]
This converts all items of the food list to lowercase
for i in range(len(foodlists)):
foodlists[i] = foodlists[i]. lower()
Prompt the user for food. When user inputs Q or q, the program exits
food = input("Food (Q to quit): ").lower()
This is repeated until the user quits
while food != "q":
Check and print the status of the food
print("Status: ",checkstatus(food,foodlists))
Prompt the user for another food
food = input("Food (Q to quit): ").lower()

The following Mic1 microcode excerpt shows support for a possible 7 bit opcode, 8 bit integer argument machine instruction (organized like the INSP instruction). This part of the microcode will be reached after the instruction opcode has been parsed and identified by earlier parts of the microcode and while the IR contains the complete instruction from memory (as usual for the IR).
100:a := band(smask, ir);
101:a := a + (-1); if n goto 0;
102:ac := lshift(ac); if n goto 104;
103:goto 101;
104:ac := ac + 1; goto 101;
If this possible instruction had a masm assembly pneumonic of XXXX , and was used in an assembly program as shown below:

d. 0 0 1 1 0 1 1 1 1 0 1 1 0 1 1 0
Answer:
The answer is "Option A".
Explanation:
In the first 2 signatures in a string, the "ol" with both the "l" throughout the low byte environment is included, and so the initial bit layout becomes: Number of [tex]0 1 1 0 1 1 1 1 0 1 1 0 1 1 0 0[/tex] Its high 7 bits are moved to the lower 7 having come until the correct circular change of 7 is done:

What is output? public class MathRecursive { public static void myMathFunction(int a, int r, int counter) { int val; val = a*r; System.out.print(val+" "); if (counter > 4) { System.out.print("End"); } else { myMathFunction(val, r, counter + 1); } } public static void main (String [] args) { int mainNum1 = 1; int mainNum2 = 2; int ctr = 0; myMathFunction(mainNum1, mainNum2, ctr); } }
a) 2 4 8 16 32 End
b) 2 2 2 2 2
c) 2 4 8 16 32 64 End
d) 2 4 8 16 32
Answer:
The output of the program is:
2 4 8 16 32 64 End
Explanation:
See attachment for proper presentation of the program
The program uses recursion to determine its operations and outputs.
The function is defined as: myMathFunction(int a, int r, int counter)
It initially gets the following as its input from the main method
a= 1; r = 2; counter = 0
Its operation goes thus:
val = a*r; 1 * 2 = 2
Print val; Prints 2
if (counter > 4) { System.out.print("End"); } : Not true
else { myMathFunction(val, r, counter + 1); }: True
The value of counter is incremented by 1 and the function gets the following values:
a= 2; r = 2; counter = 1
val = a*r; 2 * 2 = 4
Print val; Prints 4
else { myMathFunction(val, r, counter + 1); }: True
The value of counter is incremented by 1 and the function gets the following values:
a= 4; r = 2; counter = 2
val = a*r; 4 * 2 = 8
Print val; Prints 8
else { myMathFunction(val, r, counter + 1); }: True
The value of counter is incremented by 1 and the function gets the following values:
a= 8; r = 2; counter = 3
val = a*r; 8 * 2 = 16
Print val; Prints 16
else { myMathFunction(val, r, counter + 1); }: True
The value of counter is incremented by 1 and the function gets the following values:
a= 16; r = 2; counter = 4
val = a*r; 16 * 2 = 32
Print val; Prints 32
else { myMathFunction(val, r, counter + 1); }: True
The value of counter is incremented by 1 and the function gets the following values:
a= 32; r = 2; counter = 5
val = a*r; 32 * 2 = 64
Print val; Prints 64
if (counter > 4) { System.out.print("End"); } : True
This prints "End"
So; the output of the program is:
2 4 8 16 32 64 End

In the recursive function findMatch(), the first call is findMatch(array, 0, 4, key) . What are the remaining function calls to find the character 'e'?
public class FindMatch {
public static int findMatch(char array[], int low, int high, char key) {
if (high >= low) {
int mid = low + (high - low) / 2;
if (array[mid] == key) {
return mid;
}
if (array[mid] > key) {
return findMatch(array, low, mid, key);
}
else {
return findMatch(array, mid + 1, high, key);
}
}
return -1;
}
public static void main(String args[]){
char array[] = {'a','b','c','d','e'};
char key = 'e';
int result = findMatch(array, 0, 4, key);
if (result == -1) {
System.out.println("Element not found!");
}
else {
System.out.println("Element found at index: " + result);
}
}
}
a. (array, 2, 4, key) and (array, 3, 4, key)
b. (array, 2, 4, key), (array, 3, 4, key) and (array, 4, 4, key)
c. (array, 3, 4, key)
d. (array, 3, 4, key) and (array, 4, 4, key)
Answer:
The answer is "Option D".
Explanation:
In the given question "(array, 3, 4, key) and (array, 4, 4, key)", the element 'e' to also be searched is concentrated mostly on the right-hand side of the array since it is in the last place. This same middle value is 2 but findMatch(array, mid + 1 high, key) is labeled twice to move the center pointer to its last position, that is, so move that search item's 'e.'

Explanation:
Write a Python code that takes two sequences CATCGTCCT and CACCGACCG and prints the point mutations found when aligning the two sequences. Tip: you simply need to write a for loop to go over the length of the sequences, pick a letter from each position,and, compare the two sequences position by position for matches and report the mismatches.
Answer:
Following are the code to the given question:
def match_sequence(s1,s2):#Defining a method match_sequence that accepts two parameters
for l in range(len(s1)):#defining a loop that checks range of s1 value
if(s1[l] != s2[l]): # use if block to match each sequences
print('The sequence does not match at index: ',l+1)#print value with message
s1 = 'CATCGTCCT'#defining a string varible s1
s2 = 'CACCGACCG'#defining a string varible s1
match_sequence(s1,s2)#calling a method that prints its values
Output:
The sequence does not match at index: 3
The sequence does not match at index: 6
The sequence does not match at index: 9
Explanation:
In this code, a method "match_sequence" is declared that takes two string variable "s1 and s2" in its parameters, and inside the method, a loop is declared that checks the range of s1 value and use if block to match each sequence and use a print method that prints it values.
Outside the method, two string variables are declared that holds a string value that passes into the "match_sequence" method and calls it.
