Online C Compiler

How This Works:

1. Write or paste C code in the editor
2. Click "Compile & Run" to see simulated output
3. Use "Save to Cloud" for simulated storage
4. For real compilation, see offline instructions

Note: This is a browser simulation. Real compilation requires a server.

C Code Editor

#include <stdio.h> int main() { printf("Hello, World!\n"); return 0; }

Output

C Code Examples

1. Hello World

#include <stdio.h>

int main() {
    printf("Hello, World!\n");
    return 0;
}

2. Fibonacci Sequence

#include <stdio.h>

int main() {
    int n = 10, t1 = 0, t2 = 1, nextTerm;
    
    printf("Fibonacci Series: ");
    for (int i = 1; i <= n; ++i) {
        printf("%d, ", t1);
        nextTerm = t1 + t2;
        t1 = t2;
        t2 = nextTerm;
    }
    return 0;
}

Real C Compilation Instructions

To actually compile C code on your computer:

Windows:
