编写程序求 number 的阶乘。number 的阶乘等于1*2*...*number，比如，5的阶乘等于1*2*3*4*5，结果为120。Python语言用for循环

即可实现，代码如下：

number = int(input("请输入一个整数："))
factorial = 1
for i in range(1, number+1):
    factorial *= i
print(number,"的阶乘是：",factorial)

请注意，输入的应该是一个正整数，否则程序会报错。

编写程序求 number 的阶乘。number 的阶乘等于1*2*...*number，比如，5的阶乘等于1*2*3*4*5，结果为120。Python语言

可以使用递归来计算 number 的阶乘。下面是使用 Python 语言编写的程序：

def factorial(number):
    if number == 1:
        return 1
    else:
        return number * factorial(number - 1)

# 测试
print(factorial(5))  # 输出 120

C语言计算n的阶乘；计算1*3*5*7*....*(2n+1)

Sure, I can help you with that. Here's a code snippet in C language to calculate the factorial of n:

#include <stdio.h>

int main() {
  int n, i, factorial = 1;

  printf("Enter a number: ");
  scanf("%d", &n);

  for (i = 1; i <= n; i++) {
    factorial *= (2*i - 1);
  }

  printf("Factorial of %d is %d\n", n, factorial);

  return 0;
}

This program uses a `for` loop to iterate through the odd numbers (`2n-1`) up to `2n-1`, and multiplies them together to calculate the factorial of n.
