There are times when we write codes according to problem statement, Run it, and never be able to debug it.
Error: Illegal Use Of Floating Point is one such error. The problem is with the % operator you have used.
We all use '%' operator known as modulus operator in C. Lets focus on some facts about it :
- % operator gives Remainder of Division of the two numbers.
Ex. 20 % 3 = 2 - On focusing a bit it will be clear that % operator gives its value in an int form.
- Hence its defined only for integer type variables. The above error occurs because you ave used % with a float type variable or constant.Ex #1:
#include<stdio.h>main(){int a=20,b=3,c; //NO ERRORc=a%b;printf("%d",c);}
####No Error Output = 2
Ex #2:#include<stdio.h>main(){float a=20,b=3,c;c=a%b;printf("%f",c);}
###Error illegal use of floating point - If you want to use it with float values only then there is a solution for it too:
use of fmod() Function defined under <math.h> library.
