💻 Program Code

#include <stdio.h>
int main()
{
	int j=0;
	do
	{
		printf("Value of variable j is: %d\n", j);
		j++;
	}while (j<=3);
	return 0;
}

🖥 Program Output

Value of variable j is: 0
Value of variable j is: 1
Value of variable j is: 2
Value of variable j is: 3

📘 Explanation

A do while loop is similar to while loop with one exception that it executes the statements inside the body of do-while before checking the condition. On the other hand in the while loop, first the condition is checked and then the statements in while loop are executed. So you can say that if a condition is false at the first place then the do while would run once, however the while loop would not run at all.

🎯 How to learn from this example

First understand the algorithm carefully. Then study the program line-by-line and compare it with the output. Finally, review the explanation section to strengthen your logic and programming understanding.

🔥 Practice suggestion

Rewrite the program without looking at the code. Modify values, conditions or logic and run it again. This helps improve confidence and strengthens coding skills much faster.
