c++异常处理

 #include <iostream>using namespace std;double div(const double source,const double destination){if(destination == 0)throw 1;return source/destination;}int length(char *arr){int count=0;for(int i=0;arr[i]!='/0';i++)count++;return count;}char array(char *arr,int i){if(i>=length(arr))throw 1.0;return arr[i];}void main(){double a,b;char *arr = new char(10);for(int i=0;i<10;i++)arr[i]='a'+i;cout<<"please enter two numbers:";cin>>a>>b;while(true){try{cout<<div(a,b)<<endl;for(int j=0;j<=10;j++)cout<<array(arr,j)<<endl;return;}catch(int){cout<<"iVALID!please enter agian:";cin>>a>>b;}catch(double){cout<<"you are accessing Ivalid array!"<<endl;return;}}}

 

看了c++标准程序库里的异常的东西，写了个小程序，处理被0除和数组越界异常。
