Function with arguments, no return value Dry Run in C

Function with arguments, no return value is an interactive C dry run visualizer from the Functions 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.

#include <stdio.h>

void displaySum(int a, int b);  // takes two integers, returns nothing

int main() {
    int x = 10, y = 20;
    displaySum(x, y);   // passing arguments
    return 0;
}

void displaySum(int a, int b) {
    int sum = a + b;
    printf("Sum of %d and %d = %d\n", a, b, sum);
