Write a c++ program. Make sure your program handle all validations Use at Least One class. C= 1/b + 2 / (a+1)

Question

#include<cstdlib>
#include<iostream>
#include<math.h>

using namespace std;

class Coding{
private:
double a, b, c;
public:
void display();
Coding(){
cout<<"Enter the value for a: ";
cin>>a;
cout<<"Enter the value for b: ";
cin>>b;
if(a!=-1)
{
cout<<"a cannot be -1" ;
}
if (b!=0)
{
c=(1 / b) + 2 / (a + 1);
cout<<"c = ";
cout << c << endl;
}
else{
cout << "b cannot be zero: ";
}
}

};
int main(){
Coding myCoding;
myCoding.display( value a, value b);
}

Answer 1

you have not defined the display function. Also what is value a, value b?

in your constructor there is assignment to private variables a and b, they are not visible outside your class. you can call display() without arguments and print a and b inside display function.

also i believe there is logic error for (a != -1) because if value cannot be -1 it should be a == -1. but if you are checking for negative values a < 0 is better.
