Consider the following for loop. (4)  int j, s; s = 0; for (j = 1; j <= 10;=”” j++)   =”” s=”s” +=”” j=”” *=”” (j=”” -=”” 1); =””> In this for loop, identify the loop control variable, the initialization statement, loop condition, the update statement, and the statement that updates the value of s.

What is the output of the following program segment?  (4)  long long num = 5; int i; for (i = 1; i < 3;=”” i11)=””>     num = num + num * (num – i);     cout < num=””>< “=”” “;=””>  cout <> What is the output of the following program segment?  (4)  int num

Assume that the following code is correctly inserted into a program:  (4)  int num = 1; int count; for (count = 0; count < 5;=””>     num = 2 * num + num % (count + 1); a. What is the final value of num?  (i) 15                      (ii) 42                     (iii) 26                    (iv)

Write a for statement to add all the numbers divisible by 3 or 5 between 1 and 1000.  (4) What is the output of the following code? Is there a relationship between the variables x and y? If yes, state the relationship? What is the output?  (4) int x = 19683;  int i; int y

State what output, if any, results from each of the following statements:  (4) a. for (i = 1; i <= 1;=”” i++)=””> cout < “*”;=””> cout <> b. for (i = 2; i >= 1; i++)  cout <>  cout <> c. for (i = 1; i <= 1;=””>    cout <>    cout < endl;=””>

What is the output of the following code? (4) for (int k = 2; k <= 10000;=”” k=”k” *=”” k) =””>cout < k=””>< “=”” “;=””> cout <> What is the output of the following C++ program segment? Assume all variables are properly declared. (4) for (j = 0; j < 8;=”” j11)=””> cout < j=””

The following program contains errors that prevent it from compiling and/or running. Correct all such errors. (4) #include #using namespace sdt; const int LIMIT = 35; int main();     long long num1, num2:     double first, second;     cout >> “Enter two integers less than 100: “”     cin < num1=””>> num2;     cout >> endl;

Suppose that the input is 6 -2 4 9 -5 8. What is the output of the following code?  (4) int num, count, temp = 1; cin >> num; for (count = 1; count <= 4;=”” count++)=””>     temp = temp + temp * (num + count);     cin >> num; cout “temp=””> >

Write an input statement validation loop that prompts the user to enter a number less than 20 or greater than 75.   (2, 4, 5) Rewrite the following as a for loop. (2, 4) int i = 0, value = 0; while (i <= 20)=””>     if (i % 2 == 0 && i <=>         value

What is the difference between a pretest loop and a posttest loop? (2, 4, 5) How many times will each of the following loops execute? What is the output in each case?  (5) a. x = 5;  y = 50;  do     x = x + 10;  while (x <>  cout < x=””>< “=”” “=””><
