// Reverse String with strrev
#include <stdio.h>
#include <string.h> // Required for strrev and strlen (on systems where strrev is available)

int main() {
    // Step 1: Declare and initialize a character array (string)
    char str[] = "hello world";
    printf("Original string: %s\n", str);

    // Step 2: Reverse the string using strrev
    // NOTE: strrev is non-standard and might not be available on all compilers (e.g., GCC)
    strrev(str);

    // Step 3: Print the reversed string
    printf("Reversed string: %s\n", str);
