Remove Illegal error and class cannot return a value

#include<iostream.h>

I not really familar with C++, but the error seems like you trying to return a value in void function, which is illegal.

Try replace the void with the return value datatype.

float Saltax::get() {
    cout << "Enter the salary:";
    cin>>x;
    return x;
}

Don't forget to change this

float get();

Also, I don't think void main() is allowed in C++. Shouldn't it be int main() ?
