// String Concatenation Example
#include <stdio.h>
#include <string.h> // Required for strcat()

int main() {
    // Step 1: Declare a destination string with initial content and sufficient capacity
    // Ensure destination buffer is large enough for both strings + null terminator
    char greeting[30] = "Hello"; 
    
    // Step 2: Declare a source string to append
    char name[] = " World!";

    // Step 3: Concatenate name to greeting using strcat()
    strcat(greeting, name);

    // Step 4: Print the combined string
    printf("Combined string: %s\n", greeting);

    // Note: strcat also does not check buffer size,
    // potentially causing buffer overflow. For safer concatenation, use strncat().

    return 0;
