- Trace the following and select which output matches your output from your trace: #include <iostream> using namespace std; int main() { int x, y; int *p = &x; int *q = &y; x = 62; y = 38; *p = 55; cout << x << " " << y << endl; cout << *q << " " << *p << endl; return 0; }A semicolon (;) is necessary at the end of which type of the loop?

- in python for glass box testing of a while loop, you should test cases where: a) the while loop is not entered b) the body of the while loop is executed just once c) the body of the while loop is executed more than once e) all of these f) exiting the loop in the middle of the bodyWhat does the following code segment output? Assume that a variable is declared. int x= 5; for (; ; x++) { if (x < 6) 11 cout<< x << else break; } A. 5 6 В. 5 C. 6 D. ErrorThe program segment has errors. Find as many as you can. // This code should use a loop to raise a number to a power. int num, bigNum, power, count;cout << "Enter an integer: "; cin >> num; cout << "What power do you want it raised to?

- 6. infave = Given the following code segment, what is the output? int x = 1, y = 1, z = 1; %3D Y - y + z; x = x + y: cout <« "result = " << (x < y ? y: x) <« endl;This program in C++ obtains a series of letter grades as input from a user. The program should calculate and output the total grade points and the grade point average (note: you may have to track the total number of inputs and the grade points to calculate the grade point average). The algorithm should execute 3 times for testing purposes.Use the appropriate loop for the main structure of the program that will stop accepting letter grades when the user inputs X. Also, choose the appropriate selection statement to convert the letter grade to the correct grade points.Additional Requirements:• Use appropriate data types and variable names throughout the code.• Use constants appropriately. Output needs to look like the image below.Please answer all questions for the while loop: while loop x=9; // loop variable while (x>0) { cout << x <<” , “ endl; x = x - 1;// update } Questions: 1.What is the name of loop variable, or loop control variable? 2.How many iterations does the loop do? 3What is initial value of count? 4.What is value of i when the loop exits (fails) 5.What is the output of the code?
