int main()
{
    int n,m,i,s=1,j,b=0;
    scanf("%d",&m);
    int a[m];
    for(i=0;i<m;i++)
    {
        scanf("%d",&n);
        for(j=1;j<=n;j++)
        {
            b++;
            s*=b;
        }
        a[i]=s;
        s=1;
        b=0;
    }
    for(i=0;i<m;i++)
    printf("%d\n",a[i]);


    return 0;
}

Solution C++

   if(i<=n){t=t*i;
             i=i+1;
            }
  printf("%d\n",t);
 }
  return 0;
