Thread: Homework Help! Please!

Im a beginner and i need help on an assignment due at midnight.

1) Find workers pay if rate is $9.00 and they get overtime (1.5x) after 40 hours

Code:

#include <stdio.h>


int main(){
  int hours;
  double pay;
  
  printf("Enter the number of hours: \n");
  scanf("%d", &hours);
  
  if(hours>40){
  pay = hours*9.00*1.5;
  }
  else if(hours<=40){
  pay = hours*9.00;
  }
  printf("Your pay is %.2f", &pay);
  
  return 0;
  
}

This first one returns $0.00 no matter how many hours you put in.



2) Write program that will transcript message based on GPA

0-0.99 Failed
1-1.99 Suspended
2-2.99 no message
3-3.5 dean's list
4-4.0 highest scholar award

Code:

#include <stdio.h>


int main(){
  
  double GPA;
  
  printf("Enter your GPA: \n");
  scanf("%d", GPA);
  
  if(GPA <= 4.0 && GPA >= 3.5)
    printf("Highest honors for semester\n");
  else if(GPA < 3.5 && GPA >= 3.0)
    printf("Dean's list for semester\n");
  else if(GPA < 3.0 && GPA >= 2.0)
    printf("\n");
  else if(GPA < 2.0 && GPA >= 1.0)
    printf("On probation for next semester\n");
  else if(GPA < 1.0)
    printf("Failed semester - Registration suspended\n");
    
    return 0;
}

This one always returns the last line even if you put in a 4.0 GPA for example

1. Instead of "using else if" you can use just "else" for the last condition. Keeps the program simpler.
2. There is no need to declare the variables as double in your case. Using float and scanf it with %f would suffice.
3.When printing you don't use &. YOu don't need to print the address.
Just do it as printf("pay is", pay);
