Write the C++ code for computing the result for b2 -4ac. (logic explained step by step)

Here is the C++ code  for computing the result for b2 -4ac. .It takes input for the variables a,b and c and calculates the result. You all should have in mind how it works exactly. Here is the algorithm.

  Steps

User side

1: User asked to enter the values for the variable 'a', 'b' and 'c'

2: Screen shows the calculated result.

Developer side

1: Declare variables that are going to be used in program .

2: Input the values for the variable 'a', 'b' and 'c' from user.

3: Calculate the formula using following statement 

   x=(b*b)-(4*a*c);

4: Show the value of 'x'.

5: Program ends here.

Code:

#include <iostream>

using namespace std;

int main()

{  int a,b,c;

    float x;

    cout<<"Enter a= ";

    cin>>a;

    cout<<"Enter b= ";

    cin>>b;

    cout<<"Enter c= ";

    cin>>c;

    x=(b*b)-(4*a*c);

    cout<<"Result="<<x<<endl;

   system("pause");

   return 0;

}

Output:
