C++ Error: ISO C++ Forbids Comparison Between Pointer and Integer [-fpermissive]

Question

I am a beginner C++ Programmer With Very little knowledge about C++. I Have Been Creating a Program on The IDE and Compiler: Dev-C++ 5.6.3. I have run into this error: ISO C++ Forbids Comparison Between Pointer and Integer [-fpermissive]. I don't know what it means but I will put the whole code here:

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

using namespace std;
// This is the Cleaner and Updated version of the test program.

int main(int argc, char** argv) {

Answer 1

"Y" , "y" , "n" , and "N" are C-style strings, which are null-terminated character arrays. When attempting to compare them, they degenerate to pointers to const char . On the other hand, inputy is declared as int . This is the origin of your comparison between pointer and integer errors.

To fix the issue, compare inputy against characters instead of strings: 'Y' , 'y' , 'n' , and 'N' (note the single quotes, rather than double quotes).

Answer 2

You have another problem. You've declared int inputy; but you are trying to read a character by doing scanf("%c", &inputy); . The format string %c does not match the data type of &inputy . If you want to read a character you should use the correct type for the input variable:

char inputy;

scanf("%c", &inputy);
