This is a code in C to find the average word length but it does not work beyond case 1.......why?

Question

#include <stdio.h>
#include<string.h>
int main() {
int l,s;
char a[100]={0};
fgets(a,100,stdin);
for(int i=0;i<98;++i)
{
if((a[i]<=90 && 65<=a[i]) || (a[i]<=122 && a[i]>=97))
{
l++;
}
}
for(int i=0;i<98;++i)
{
if(a[i]==' ')
{
s++;
}
}
float c;
c=(l/(s+1))+0.5;
int d;
d=c;
printf("%d",d);
return 0;
}

Answer 1

Round up means 3.000000000001 becomes 4 or ceiling. Your code is doing a normal round. Use ceil for it.
