Pass structure to function (by value) Dry Run in C

Pass structure to function (by value) is an interactive C dry run visualizer from the Struct Functions Pointers 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.

Pass structure to function (by value) Program Code

#include <stdio.h>
#include <string.h>

struct Student {
    int roll;
    char name[50];
    float marks;
};

void displayStudent(struct Student s) {
    printf("Roll: %d\n", s.roll);
    printf("Name: %s\n", s.name);
    printf("Marks: %.2f\n", s.marks);
}

int main() {
    struct Student s1 = {101, "John Doe", 85.5};
    displayStudent(s1);
    return 0;
}
