Your code seems a bit muddled. For one thing, it looks like an attempt to define one function inside another, that's not possible.

This is a general idea of how it might look, though I've not attempted to use your example.

#include <iostream>

using namespace std;

int square(int);

//----------------------------------------
int main ()
{
    int number;

    cout << "Please enter a number" << endl;
    cin >> number;

    int squ = square(number);
    cout << "Square of " << number << " is " << squ << endl;

    system ("pause");
    return 0;
}

//------------------------------------------

int square(int x)
{
    return x * x ;
}
