How do you store 100 factorial?

Factorial of 100 has 158 digits….factorial(n)

1. Create an array ‘res[]’ of MAX size where MAX is number of maximum digits in output.
2. Initialize value stored in ‘res[]’ as 1 and initialize ‘res_size’ (size of ‘res[]’) as 1.
3. Do following for all numbers from x = 2 to n.

Which data type can store 100 factorial?

use double instead of long long int, as for 100!, long long int is too short to hold the result.

How many digits does 100 factorial have?

158 digits
But Factorial of 100 has 158 digits.

How do you find the factorial of an integer?

To find the factorial of a number, multiply the number with the factorial value of the previous number. For example, to know the value of 6! multiply 120 (the factorial of 5) by 6, and get 720.

How do you find the number of zeros in 100 factorial?

Each pair of 2 and 5 will cause a trailing zero. Since we have only 24 5’s, we can only make 24 pairs of 2’s and 5’s thus the number of trailing zeros in 100 factorial is 24.

How do you find the factorial of a large number?

Factorial of a large number 1 Create an array ‘res []’ of MAX size where MAX is number of maximum digits in output. 2 Initialize value stored in ‘res []’ as 1 and initialize ‘res_size’ (size of ‘res []’) as 1. 3 Do following for all numbers from x = 2 to n.

What is the factorial of 100?

The factorial of 100 (100!) is 93326215443944152681699238856266700490715-. 9682643816214685929638952175999932299156089-. 4146397615651828625369792082722375825118521-. 0916864000000000000000000000000 which is 158 digits long and the maximum value of unsigned long long int in C is 18,446,744,073,709,551,615.

How will we store a very large integer value in C?

Originally Answered: How will we store a very large integer value, say 100!, in C? There’s no data type in C to store such a big integer. But you can use an array (of integers),which acts like a single integer.Keep computing and modifying the result within the array itself until you get to the factorial of the desired number.

What is the best way to handle factorials?

As factorials can rapidly exceed the range of standard fixed width integers and even floating point types like double, Code should consider a user type that allows for unbounded integer precision for an exact answer. Various wide integer precision libraries exist, yet if code needs a simple solution, consider using a string.
