my program stops right before the while loop
#include <stdio.h>
int main()
{
int pay_type_1;
int overtime;
int num;
float commissionsale;
float payperitem;
float salary;
float hourrate;
const float commissionrate=0.057;
const float commissionpay=250;
const float overtimerate=1.5;
printf("paytype1=Managers salary\n");
printf("paytype2=hourly worker\n");
printf("paytype3=commision worker\n");
printf("paytype4=piece worker\n");
while (pay_type_1 > 0)
{
printf("enter pay type number from above\n (-1 to end)");
scanf("%d",&pay_type_1);
switch(pay_type_1)
{
case 1:
printf("Enter manager' fixed salary\n");
scanf("%f",&salary);
break;
case 2:
printf("Enter hourly rate for paytype two worker\n");
scanf("%f",&hourrate);
printf("enter overtime hours worked by the paytype two worker\n");
scanf("%d",&overtime);
salary=(hourrate*40)+(overtime*(hourrate*overtime));
break;
case 3:
printf("enter total sales from paytype three worker\n");
scanf("%f",&commissionsale);
salary=commissionpay+(commissionsale*commissionrate);
break;
case 4:
printf("enter nuber of item made by paytype four worker\n");
scanf("%d",&num);
printf("enter pay per item\n");
scanf("%f",&payperitem);
break;
}
printf("Salary:%7.2lf\n",salary);
}
}can you see and tell me why its not working. thanks
