我输入了这个,它要求用户输入两个整数,然后变成变量.从那里它将执行简单的操作.
如何让计算机检查输入的内容是否为整数?如果没有,请让用户键入一个整数.例如:如果有人输入"a"而不是2,那么它会告诉他们重新输入一个数字.
谢谢
#include <iostream>
using namespace std;
int main ()
{
int firstvariable;
int secondvariable;
float float1;
float float2;
cout << "Please enter two integers and then press Enter:" << endl;
cin >> firstvariable;
cin >> secondvariable;
cout << "Time for some simple mathematical operations:\n" << endl;
cout << "The sum:\n " << firstvariable << "+" << secondvariable
<<"="<< firstvariable + secondvariable << "\n " << endl;
}
