Large Factorials

 C program to find factorial of a number N <= 100 .

#include<stdio.h>
int main()
{
    int t;
    scanf("%d",&t);
    while(t--)
    {
        int a[200],m=0,i,k,n,temp=0;
    scanf("%d",&n);
        a[0]=1;
        m=1;
        while(n>1)
        {
            for(i=0;i<m;i++)
            {
                k=((a[i]*n)+temp);
                a[i]=k%10;
                temp=k/10;
            }
            while(temp>0)
            {
                a[m++]=temp%10;
                temp/=10;
            }
            n--;
        }
        for(i=m-1;i>=0;i--)
            printf("%d",a[i]);
        printf("\n");
    }
    return 0;
}
