Question

In what sequence the initialization, testing and execution of body is done in a do-while loop?

Make a short program to justify your selection.


a: Initialization, execution of body, testing
b: Execution of body, initialization, testing
c: Initialization, testing, execution of body
d: None of the above

Answer 1

a: Initialization, execution of body, testing

let counter = 5

do {

counter++

console.log("I will run once without testing for condition")

}

while (counter < 5);

Answer 2

In do-while loop the execution of the body happens before the testing process. So option 'a' is the correct answer.

Here is an C++ example of the do-while loop that justifies its execution process:

#include<iostream>

using namespace std;

int main()

{

//initialization    

int n=5;  

do{

 //execution of the body

    cout<<" The Answer is:" <<" " <<n;

}

//testing of the condition

while(n>5);

return 0;

}

Output: The Answer is: 5

Here, the condition is false, but the control or flow of the program goes like: initialization, execution, and then the testing.

In do- while loop condition is checked at the at end of the loop. It means even if the condition is false the statement written inside the body of loop will be executing at least for once.
