No matching function for call

[Maniax]

Hello :)
I'm getting this error No matching function for call to 'input' here's my code:

Header.h

#include <iostream>
void input(int &a, const char * error = ""); //Some functions and classes

class SQUARE
{
private:
    double side;
    double area;
    double diagonal;
    double perimeter;
public:
    void populate();
};

Functions.cpp

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

void input(int &a, const char * error)       //Check for correct input
{
    using namespace std;
    
    while (!(cin >> a))
    {
        cin.clear();
        while (cin.get() != '\n') continue;
        cout << "Invalid Value! " << error << endl;
    }
}

void SQUARE::populate()                            //Populate class
{
    using namespace std;
    cout << "Enter the side of the square: ";
    input(side, "Please enter an integer: ");      //The error shows up here.
}

//Silly question

Thanks in advance :P

Look at the parameters of input(), now have a look at the parameters you are passing to it.

You may have other problems, but here's one hint:

void input(int &a, const char * error)

class SQUARE
{
private:
    double side;

input(side, "Please enter an integer: ");

edit: ah, beaten!

What a silly mistake >.> Thanks sloppy9 and ReedTompkins

Solved

template <class any>
void input(any &a, const char * error)
{
    using namespace std;
    
    while (!(cin >> a))
    {
        cin.clear();
        while (cin.get() != '\n') continue;
        cout << "Invalid Value! " << error << endl;
    }
}

is it head or header if its header then there is part of the problem also the arguements arent defined in the header
