How to calculate factorial?

Factorial is the multiplication from 1 times 2 times 3 times 4 to the required number
If the required number is 4, then the factorial formula is 1 × 2 × 3 × 4, and the product obtained is 24. For example, if the required number is n, then the factorial formula is 1 × 2 × 3 × Let X be the product of X

On finding factorials Write a program to calculate the following formula and output the results requirement: (1) Write a factorial n! Function fact (n), (can use cumulative multiplication, can also use recursive method) (2) Write the main function, input n and m by keyboard, and complete the calculation through nested call (1) (3) Input n and m should give a prompt, and check the rationality of N and M. unreasonable input should output error information and no longer be calculated (4) Run the program and verify that it is correct #include int fact(int n) { int i,a=1; for(i=1;i

This is a program I wrote recursively. ා include int fact (int n) {if (n = = 0 | n = = 1) return 1; else return n * fac (n-1);} int main() {int m, N, sum; printf ("please input m, n); scanf (% d% d", & M, & n); if ((n

It is proved that 2 ^ 155-1 can be divisible by 961

Firstly, it is proved that if n > = 1,2 ^ 5n-1 can be divisible by 31, using mathematical induction: let K (n) = 2 ^ 5N - 1, if n = 1: K (1) = 2 ^ 5 - 1 = 31, suppose: 2 ^ 5N - 1 can be divisible by 31, then: K (n + 1) = 2 ^ 5 (n + 1) - 1 = 2 ^ 5N * 2 ^ 5 - 1 = 32 * 2 ^ 5N - 1 = (2 ^ 5N - 1) + 31 * 2

Prove that 5 ^ n-1 is divisible by 4

It is proved by mathematical induction that 1) when n = 1, 5 ^ 1-1 is divisible by 4; 2) if n = K (k is a natural number), if 5 ^ k-1 is divisible by 4, then when n = K + 1, 5 ^ (K + 1) - 1 = 5 * 5 ^ k-1 = 4 * 5 ^ k + 5 ^ k-1 ∵ 4 * 5 ^ k is obviously divisible by 4, 5 ^ k-1 is divisible by 4 ? 4 * 5 ^ k-1 is divisible by 4 ? 4 * 5 ^ k + 5 ^ k-1 is divisible by 4
