A program uses a char variable named department and two double variables named salary and raise. The department variable contains one of the following letters (entered in either uppercase or lowercase): A, B, or C. Employees in departments A and B will receive a 2% raise. Employees in department C will receive a 1.5% raise. Write a C++ program to calculate and display the appropriate raise amount. Display the raise amount in fixed-point notation with two decimal places.

Here is the Solution to the problem above:

#include <iomanip>
#include <iostream>

using namespace std;
int main(int argc, char *argv[])
{
    char department;
    double salary;
    double raise;
    
    cout<<"Enter the employee's department: ";
    cin>>department;
    cout<<"Enter the employee's salery: ";
    cin>>salary;
    
    if(department == 'A'||department == 'a')
    {
        raise = salary/100*2;
    }
    else if(department == 'B'||department == 'b')
    {
        raise = salary/100*2;
    }
    else if(department == 'C'||department == 'c')
    {
        raise = salary/100*1.5;
    }
    
    cout<<"Employee's pay raise by: ";
    cout << setprecision(2) << fixed << raise;
    return 0;
}
