程序在Ubuntu 14.04和GCC中无法正确编译

Question

I recently dual-booted my Windows PC with Ubuntu 14.04 LTS and I'm using Code::Blocks as my IDE of choice and GCC as my compiler.

I'm a Java programmer learning C++ and I wrote a simple addition program that takes two numbers and adds them together. When I run the program I put in the first number then the second number and instead of telling me my answer, it skips that and I just hit enter and end the program.

Here's my code:

#include <iostream>

using namespace std;

int main()
{
  int thisisanumber;
  int thisisanothernumber;
  int outputnumber;

  cout<<"Please enter first number: ";
  cin>>thisisanumber;
  cin.ignore();
  cout<<"Please enter second number: ";
  cin>>thisisanothernumber;
  cin.ignore();

  outputnumber = thisisanumber + thisisanothernumber;

  cout<<"Your answer is: "<< outputnumber <<"\n";

}

Answer 1

It sounds like you're running your program in an environment that closes the terminal window when the program has finished. If you're using Code::Blocks, you'll want to take these steps.

Go to Project -> Properties -> Build targets

Make sure your target is of type Console project and you have checked Pause when execution ends .
