c++ - 如何将分数拆分为两个整数 C++

Question

我正在做一项作业。我需要让用户以 #/# 格式输入分数。如何将顶部和底部设置为两个单独的变量？

这是我试过的一段代码，但我一直没有得到第二个变量的任何信息:

#include <iostream>
#include <conio.h>
#include <cstdio>
#include <regex>

using namespace std;

int main() {
    string firstFraction;

    cout << "Enter your first real Fraction: " << endl;
    firstFraction = cin.get();

    string delimiter = "/";

    string numerator = firstFraction.substr(0,firstFraction.find(delimiter));

    size_t pos = firstFraction.find("/");
    string denominator = firstFraction.substr(pos); 

    cout << numerator << " / " << denominator << endl;
    _getch();
    return 0;
}

Answer 1

尝试这样的事情:

#include <iostream>
#include <string>
#include <sstream>

using namespace std;

int main() {
    string fraction;

    cout << "Enter your first real Fraction: " << endl;
    getline(cin, fraction);

    istringstream iss(fraction);

    string numerator, denominator;
    getline(iss, numerator, '/');
    getline(iss, denominator);

    cout << numerator << " / " << denominator << endl;

    cin.get();
    return 0;
}
