Very Beginner Loop question
The program reads employee number, num of shifts, and base rate from a file (each line at a time using while). then, using the for statement, depending on the number of shifts, it reads the number of hours per shift. So, if a person worked 2 shifts, the for statement would run twice, adding onto the value of "total_hours".
Code:
#include <stdio.h>
int
main()
{
int emp_num, num_shifts, i;
double base_rate, num_hours, total_hours;
while (scanf("%d %d %lf %lf", &emp_num, &num_shifts, &base_rate)!=EOF)
{
for(i=0; i<num_shifts; i++) {
scanf("%lf", &num_hours);
total_hours = total_hours + num_hours;
}
printf("%d %d %f %f %f", emp_num, num_shifts, base_rate, total_hours);
}
return(0);
}
My input file is the following: Quote:
and i used the redirection option in my compiler, by simply inputting "<input.txt". thank you for any help you can provide.

What does it mean to equate scanf statements to a value?
PHP Code:

Please explain how these above functions work.

Dude, that IS C he's writing, he just used the wrong highlighting tags. Quote:
the scanf() function returns a value, depending on the 'succes' it's had doing it's job. When things go (relatively) well, it returns the number of items read. When it can't read ALL the parameters, this value is then smaller than the number of argumenst expected. If no arguments could be read at all, it rerturns EOF (end of file). See here for more details.
