// String Copy Example
#include <stdio.h>
#include <string.h> // Required for strcpy()

int main() {
    // Step 1: Declare a source string
    char source[] = "Hello World";

    // Step 2: Declare a destination string with enough capacity
    // +1 for the null terminator. Ensure destination is large enough!
    char destination[20]; 

    // Step 3: Copy source to destination using strcpy()
    strcpy(destination, source);

    // Step 4: Print both strings
    printf("Source string: %s\n", source);
    printf("Destination string: %s\n", destination);

    // Note: strcpy does not check buffer size.
    // If destination is smaller than source, it leads to a buffer overflow.
    // For safer copying, consider strncpy().

    return 0;
