The output of this program is always incorrect. Can anyone tells me why and
correct it?? Thanks a lot!!
What's more, I would like to make the prog to reject -ve input and shows a
msg, then input again. How can I do?
(Can I use for loop only?)

#include <stdio.h>
main ()
{
int i, ppl; float rate, hr, total, pay;
 printf("Please input how many employees have overtime works: ");
 scanf("%d",&ppl);
 for(i=1;i<=ppl;i++){
 {
 printf("Please input the overtime hour of the no %d employee: ", i);
 scanf("%f",&hr);
 printf("Please input the overtime hourly rate of the no %d employee: ", i);
 scanf("%f",&rate);
 pay=hr*rate;
 }
 total+=pay;
 }
 printf("The total overtime pay is %.2f",total);
 return 0;
}
