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:...
