Simple while Loop Program

Every loop consists of three parts in sequence

  1. Initialization: Use to initialize the loop variable.
  2. Condition: It is checked after each iteration as an entry point to the loop.
  3. Updation: Incrementing the loop variable to eventually terminate the loop not satisfying the loop condition.

Here is the C language tutorial explaining while Loop → while Loop in C

Below is a simple program on while loop.


int main()
    printf("\n\n\t\tStudytonight - Best place to learn\n\n\n");

        always declare the variables before using them 
    int i = 0;  // declaration and initialization at the same time

    printf("\nPrinting numbers using while loop from 0 to 9\n\n");

        while i is less than 10 

            Update i so the condition can be met eventually 
            to terminate the loop 
        i++;    // same as i=i+1;
    printf("\n\n\t\t\tCoding is Fun !\n\n\n");
    return 0;
