int i = 0;
for(i = 0 ; i < tc ; i ++){
    
    scanf("%d",&a[i]);
    res[i] = fact(a[i]);
}

for(i = 0 ; i < tc ; i ++){
    
    printf("%d\n",res[i]);

The problem is that if the input exceeds 20 , then no primitive datatype can store the value and represent it , u can use python as it can handle large values or refer this tutorial by codechef : Tutorial for Small Factories to do it using primitive datatype in c.
