Hints

Read the line with fgets.

Use tolower so you only have to check small vowels.

Solution explanation

Turning each character to lower case first means we only need to compare against five letters.

Show solution

#include <stdio.h>
#include <ctype.h>

int main() {
    char line[201];
    fgets(line, 201, stdin);
    int count = 0;
    for (int i = 0; line[i] != '\0'; i++) {
        char c = tolower(line[i]);
        if (c == 'a' || c == 'e' || c == 'i' || c == 'o' || c == 'u') {
            count++;
        }
    }
    printf("%d\n", count);
    return 0;
}
