I was just writing a code to check whether a number is rational or irrational,please check where are the errors

Question

// For checking whether an input is rational or irrational

#include <iostream>
using namespace std;

int main()
{
float num;

cout<<"Enter the number to check : ";
cin>>num;
float remainder=num%1;
cout<<num<<endl;
if(num%1==0){
cout<<"The number is Rational and Integer";}
if(remainder%1=remainder){
cout <<"The number is Rational but its decimal representation is repeating";}
else
{cout <<"It is an Irrational number";}
return 0;
}

Answer 1

The modulo operator % only works with integral type operands. If you need to work with floating point type operands, then you will need to use `fmod` function from <cmath> header.

Answer 2

You cannot use assignment operator in if statement!
Use this '=='
