code problem

This is a code about entering the no. of test cases and finding the factorial of each case…but the codechef is not accepting this answer, can anybody please tell me whats wrong in this code…please plaese help me…i m a beginner

#include<stdio.h>
#include<stdlib.h>
long int fact(long int m)
{long int f=1;
for(int j=m;j>=1;j–)
{
f=f*j;
}
return f;
}
int main()
{
long int n,m,f;
scanf("%ld",&n);
if(n>100)
{
printf(“not valid”);
exit(0);
}
for(int i=1;i<=n;i++)
{
scanf("%ld",&m);
if(m>100)
{
printf(“invalid number”);
exit(0);
}
f=fact(m);
printf("%ld",f);
}
return 0;
}

This is because your I/O is in different format follow the format required in the question.
Note: The constraints are not to be checked by you by default tester put assert statements so you dont need to worry about the same!
