Code:

#pragma once

#include <iostream>

using namespace std;

int main()

{

    int num,cout=0;

    cout <<"Enter the number:";    //here is the error

    cin>>num;



bool done=true;

    while(done)

    {

        if (num>=10)

        {

            num=num/10;

            cout++;

        }

        else 

        {

            cout++;

            done=false;

        }

    }

printf ("%d",cout); // its working fine

system("pause");

    return 0;

}

Error: Can anyone tell me why this error is occuring, it's point at the "cout" statement.
as much as cout i m using errors are increasing.
Error 1 error C2297: '<<' : illegal, right operand has type 'const char [18]'
Warning 2 warning C4552: '<<' : operator has no effect; expected operator with side-effect

You've redefined cout as an int and set it to zero on the previous line.

The error is correct because you can't shift left an integer by a char array number of bits - this is meaningless. You can only shift an integer left by another integer.
