Generate pair combinations using while loops (while) Dry Run in C

Generate pair combinations using while loops (while) is an interactive C dry run visualizer from the Nested programs section. Study the source code, then use the execution controls to follow each step, variable update, highlighted line, and console output.

This page provides a browser-based dry run with source-code highlighting, auto-scroll, voice narration controls, and execution output for learning the program step by step.

Generate pair combinations using while loops (while) Program Code

#include <stdio.h>
int main() {
    int n, i = 1;
    printf("Enter n: ");
    scanf("%d", &n);
    
    printf("All pairs using while loops:\n");
    while(i <= n) {
        int j = 1;
        while(j <= n) {
            printf("(%d,%d) ", i, j);
            j++;
        }
        printf("\n");
        i++;
    }
    return 0;
