Example: String Copying in C

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

int main() {
    // Step 1: Declare source and destination strings
    char source[] = "Copy this text.";
    char destination[50]; // Ensure destination has enough space

    // Step 2: Use strcpy() to copy source to destination
    strcpy(destination, source);

    // Step 3: Print both strings to verify the copy
    printf("Source String: \"%s\"\n", source);
    printf("Destination String: \"%s\"\n", destination);

    // Example with strncpy for safety (copies at most n characters)
    char safe_source[] = "Too long for small buffer";
    char small_destination[10]; // Buffer size 10, meaning 9 chars + '\0'

    // Copy at most 9 characters from safe_source to small_destination
    strncpy(small_destination, safe_source, sizeof(small_destination) - 1);
    small_destination[sizeof(small_destination) - 1] = '\0'; // Manually null-terminate

    printf("\nSafe Copy Example:\n");
    printf("Source: \"%s\"\n", safe_source);
    printf("Destination (max 9 chars): \"%s\"\n", small_destination);

    return 0;
}
