// Write a program that:
// Declares a string in main (e.g., "Programming is fun").
// Passes the string to a function called count_vowels.
// The count_vowels function uses a pointer to traverse the string and 
// count how many vowels (a, e, i, o, u) are in it.
// main then prints the total number of vowels.


#include <stdio.h>
int main() {
    char sentence[] = "Programming is fun";
    int result = count_vowels(sentence);

    printf("Number of vowels: %d\n", result);

    // your turn

    return 0;
