Complete the program fragment using while statement that will display the numbers 1 to 19 ( in steps of
3, i.e. 1, 4, 7, ..., 19) with one number per output line.int number = _____ ;while (number <= 19) { cout
<< number << endl ; number = number + 3 ;} // end while

3, i.e. 1, 4, 7, ..., 19) with one number per output line.int number = 1 ;while (number <= 19) { cout <<
________ << endl ; number = number + 3 ;} // end while
Explanation
The variable "number" is being outputted on each line using the "cout" statement.

3, i.e. 1, 4, 7, ..., 19) with one number per output line.int number = 1 ;while (number <= 19) { cout <<
number << _______ ; number = number + 3 ;} // end while
Explanation
The correct answer is "endl" because it is used to insert a new line character after each number is
displayed, ensuring that each number is printed on a separate line.

3, i.e. 1, 4, 7, ..., 19) with one number per output line.int number = 1 ;while (number <= 19) { cout <<
number << endl ; _________________;} // end while
Explanation
The correct answer is "number = number + 3" or "number = (number + 3)". These statements increment
the value of the variable "number" by 3 in each iteration of the while loop. This ensures that the loop
continues until the value of "number" reaches or exceeds 19.

_______________) cout << number << endl ;
, Explanation
The correct answer is "number = number + 3" or "number = (number + 3)". These statements increment
the value of the variable "number" by 3 in each iteration of the for loop. This ensures that the program
will display the numbers 1 to 19 in steps of 3, as required by the question.

Complete the program fragment using a for statement that will display the numbers 1 to 19 ( in steps of
3, i.e. 1, 4, 7, ..., 19) with one number per output line.for (int number = 1 ; number <= 19 ; number =
number + 3) cout <<__________<< endl ;
Explanation
The given correct answer is "number". In the for loop, the variable "number" is being incremented by 3
in each iteration, starting from 1 and ending at 19. So, when we print the value of "number" in each
iteration, it will display the numbers 1, 4, 7, ..., 19.

number + 3) cout << number <<______ ;
Explanation
The "endl" statement is used to insert a new line after each number is displayed. This ensures that each
number is printed on a separate line, as required by the question.

Complete the following partially written program which is supposed to read 10 integer values using a
loop, and find the sum total of those numbers.void main () { int k, number ; int sum = 0 ; ______;
while (k <= 10) { cout << "Enter a number: " ; cin >> number ; sum = sum + number ; k
= k + 1 ; } // end while cout << "Result = " << sum << endl ;} // end main
Explanation
The correct answer is "k = 1" because the program is using a while loop to iterate 10 times and read 10
integer values. The variable "k" is used as a counter to keep track of the number of iterations. By setting
"k = 1" initially, the loop will run 10 times as long as "k" is less than or equal to 10.
