Factorial of number which can't fit in long long

#1

here sir has not discussed the way of calculating fact of large number…can u plzz explain that to me?

#2

Use the concept of array to store the factorial values, this will be the basic approach you will follow to solve your answer

#3

no…i am asking how to print that large number…ex: 100!

#4

Use the loop to print like this :
for(int i=res_size-1 ; i>=0; i–)
{
cout<<res[i];
}
Since result is stored in reverse order, you can use this approach to print

#5

the “int” can only store 4 bytes…how to print a 20 digit number…?

#6

U can use #define MAX 1000 , and then declare the size of array as MAX,
for eg res_size[MAX];
