Check if Matrix is Sparse (More Zeros than Non-Zeros) Dry Run in C

Check if Matrix is Sparse (More Zeros than Non-Zeros) is an interactive C dry run visualizer from the Two D 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.

Check if Matrix is Sparse (More Zeros than Non-Zeros) Program Code

#include <stdio.h>
int main() {
    int matrix[4][4] = {{0, 0, 3, 0}, {0, 0, 0, 0}, {1, 0, 0, 0}, {0, 0, 0, 2}}, i, j;
    int zeroCount = 0, total = 16;
    
    for(i = 0; i < 4; i++) {
        for(j = 0; j < 4; j++) {
            if(matrix[i][j] == 0) {
                zeroCount++;
            }
        }
    }
    
    if(zeroCount > total/2)
        printf("Matrix is Sparse (%.1f%% zeros)\n", (float)zeroCount/total*100);
    else
        printf("Matrix is NOT Sparse (%.1f%% zeros)\n", (float)zeroCount/total*100);
    return 0;
