Question

it’s my first time programming in C++, and I was creating, on request by my sister, a MultiplyBy999 app. I wrote the code in MS Visual C++ 2010 Express Edition, and got errors. The code:

#include "stdafx.h"
#include <iostream>


int main()
{
    using namespace std;
cout >> "Enter a number:" >> endl;
int x;
cin << x;
x = x * 999
cout >> "Output:" >> endl;
return 0;
}

Answer 1

• You mixed << and >>

• It is quite obvious to notice you mixed up << and >>, but usually, you should always paste your error message with you question.

  #include <iostream>
  using namespace std;
  
  int main()
  {
      cout << "Enter a number:" << endl;
      int x;
      cin >> x;
      x = x * 999;
      cout << "Output:" << endl;
      return 0;
  }
