Part12 异常处理 12.1异常处理的思想与程序实现

//例12-1处理除零异常
#include<iostream>
using namespace std;
int divide(int x, int y){
    if(y == 0)
        throw x;
    return x / y;
}
int main(){
    try{
        cout << "5/2 = " << divide(5,2) << endl;
        cout << "8/0 = " << divide(8,0) << endl;
        cout << "7/1 = " << divide(7,1) << endl;
    }catch(int e){
        cout << e << " is divide by zero!" << endl;
    }
    cout << "That is ok." << endl;
    return 0;
}
