OP: plenty of help on the web eg.

Something else you could consider is using just integers to hold your
values to avoid the errors you get with floating point arithmetic and
decimal fractions (such as 1244*40/100 = 497.600006, not 497.6):
#include <stdio.h>
int main(void)
{
long da_c, hr_c, i;
printf(" Enter Basic Salary = " );
scanf("%ld", &i);
da_c = i * 40; /* calculate in cents */
hr_c = i * 20;
printf("DA = %ld.%02ld and HR = %ld.%02ld\n",
da_c / 100, da_c % 100,
hr_c / 100, hr_c % 100);
return 0;
}
It's best to use long to try to avoid arithmetic overflows, which are
more likely when using integer arithmetic.
