Print “YES” (without the quotes) if all vowels are found in the string, “NO” (without the quotes) otherwise.

NO

#include <iostream>
#include <string>
using namespace std;

int main()
{
	int i,n;
	string s;
	cin >> n >> s; // n과 s를 입력받음
	int countA = 0, countE = 0, countI = 0, countO = 0, countU = 0;

	for (i = 0; i < n; i++)  // 모음들의 갯수 count
	{
		if (s[i] == 'a')
			countA++;		
		if (s[i] == 'e')		
			countE++;		
		if (s[i] == 'i')		
			countI++;		
		if (s[i] == 'o')
			countO++;		
		if (s[i] == 'u')		
			countU++;		
	}

	if (countA > 0 && countE > 0 && countI > 0 && countO > 0 && countU > 0)
		cout << "YES";
	else
		cout << "NO";
  // 모음이 모두 있으면 YES, 하나라도 없으면 0을 출력
	return 0;
}

이번 문제는 for문과 if문의 사용을 묻는 간단한 예제입니다.
