Question

Why is The following code is giving me the following compiler-error: “Cannot find a match for eat()”?

#include <iostream.h>
#include <conio.h>

void spit(char in[255])
{
    cout << in;
}

void spit (int in)
{
    cout << in;
}

int eat(int in)
{
    cout << "? ";
    cin >> in;
    return in;
}

char*  eat(char in[255])
{
    cout << "? ";
    cin >> in;
    return in;
}

int main()
{
clrscr();

int input;
input = eat(); // <---- over here
spit(input);

getch();
return 0;
}

Answer 1

You need to pass a parameter to eat

..
int input;
input = eat(123);
spit(input);
..

But why do have function eat/spit with char [255] as parameters?
You don’t use it
