Thread: Exception handling

This was my solution
but i don't know how can i detect an overflow??

Code:

#include <iostream.h>

int main(){
	
    int x;
    int eof = 0;
    int sum = 0;

    cout<<"Enter a list of integers in the range of -100 to 100 (0 to end):"<<endl;
    cin>>x;
	
      try{
        if(x<-100 || x>100)
          throw x;
        sum = x*x;}
      catch(int e){
        cout<<e<<" is out of range"<<endl;}

      while(x != eof){
        cin>>x;
        try{
          if(x<-100 || x>100)
            throw x;
          sum = sum+(x*x);}
        catch(int e){
          cout<<e<<" is out of range"<<endl;}
	}
	
       cout<<"sum of the input squares = "<<sum<<endl;
       return 0;}
