#include <iostream.h>
void main()
{
	int score;
	cout << " input score (0 for stop) : ";
	cin >> score;
	if (score >= 95)
		cout << score << ","<< "A+" << "\n";
	else if (score >= 90 && score <=94)
		cout  << score << "," << "A"  << "\n";
	else if (score >= 85 && score <= 89)
		cout << score << "," << "B+" << "\n";
	else if (score >= 80 && score <= 84)
		cout << score << "," << "B" << "n";
	else if (score >= 75 && score <= 79)
		cout << score << "," << "C+" << "\n";
	else if (score >= 70 && score <= 74)
		cout << score << "," << "C" << "n";
	else
		cout << score << "," << "F" << "\n";
}

 

설명

기초적인 소스
int 변수 score 선언
cout 로 " input score (0 for stop) : " 화면에 출력하고
cin 로 score 값 받음
if 문으로 갑 비교해서 성적 구분
