C: Program That Calculates Pay Based On Salary And Hours.
https://github.com/pereiradaniel/beginning_c/blob/master/ch2/exercises/2_4/exercise2_4.c
// Exercise 2-4
// Write a program that prompts for the user’s weekly pay in dollars and the
// hours worked to be entered through the keyboard as floating-point values. The program
// should then calculate and output the average pay per hour in the following form:
// Your average hourly pay rate is 7 dollars and 54 cents.
#include <stdio.h>
double checkInput(double input, double min, double max);
int main(int argc, char* argv[])
{
double hours = 0, rate = 0;
// Get input for hours:
printf("Enter number of hours worked: ");
while(hours == 0) {
scanf(" %lf", &hours);
hours = checkInput(hours, 1, 10000);
}
// Get input for salary:
printf("Enter hourly rate: ");
while(rate == 0)
{
scanf(" %lf", &rate);
rate = checkInput(rate, 1, 100);
}
// Calculate pay:
printf("Pay: $%.2f\n", hours * rate);
return 0;
}
double checkInput(double input, double min, double max)
{
double result = 0;
if (input < min || input > max) // out of bounds, invalid!
printf("Enter a number between %.f or %.f!\n", min, max);
else // inbounds, validate!
result = input;
return result;
