C++ not showing cout in Xcode console but runs perfectly in Terminal

Question

Basically i am running a simple program in Xcode Version 8.3 (8E162)

#include 
using namespace std;
int main() {
    int a;   
         


        

Answer 1

You already solved your problem yourself: std::cout uses buffered output and should always be flushed. You can achieve this by either using std::cout << "What is your age? << std::flush, by using std::cout.flush() or by adding a line break like std::endl which flushes implicitly.

A complete solution could look like this:

#include 

using namespace std;

int main() {
    int a;   
    cout << "What is your age: " << flush;
    cin >> a;
    cout << "My age is " << a << endl;
    return 0;
}
