C ++仅接受第一个cin输入

Question

When the program asks the user for an integer input, the user has the ability to input "4 9" and the program uses both. But what I need is for the program to only accept the first input, in this example "4".

int input;

cout << "Enter a number" << endl;
cin >> input;

Basically, the question is, how do I make sure the input does NOT have any white spaces in between integers
