使用循环是计算阶乘的一种直观方法。以下是一个使用for循环计算阶乘的C语言函数示例：cCopy code#include <stdio.h>// 函数声明unsigned long long factorial(int n);int main() { int number; printf("Enter a positive integer: "); scanf("%d", &number); // 调用函数并打印结果 printf...
Write a function to calculate the factorial of a number. The factorial of a non-negative integernis the product of all positive integers less than or equal ton. For example, the factorial of3is3 * 2 * 1 = 6. Return the factorial of the input numbernum. ...
#include <stdio.h> int factorial(int n) { // 基本情况 if (n == 0 || n == 1) { return 1; } // 递归调用 else { return n * factorial(n - 1); } } int main() { int num = 5; int result = factorial(num); printf("The factorial of %d is %d\n", num, result); retur...
}/* If sum of cubes of every digit is equal to number * itself then the number is Armstrong */if(copy_of_num == sum)printf("\n%d is an Armstrong Number",copy_of_num);elseprintf("\n%d is not an Armstrong Number",copy_of_num);return(0); } 输出: Enter a number:370370is an ...
* Input an integer number. * Output : another integer * Side effects : may blow up stack if input value is * Huge * */ int factorial ( int number) { if ( number < = 1) return 1; /* The factorial of one is one; QED * / ...
C - Check entered number is ZERO, POSITIVE or NEGATIVE C - Find factorial C - Find sum of first N natural number C - Print all prime numbers from 1 to N C - Print all even and odd numbers from 1 to N C - Print all Armstrong numbers from 1 to N C - Print square, cube and ...
h> int calcu(int x); int main() { printf("%d\n",calcu(10)); return 0; } int calcu(int x) { if (x==0) { return 1; } double factorial = x; factorial*=calcu(x-1); return factorial; } 例子2: 斐波拉契 int main() {for(int num = 1; num <= 10; num++) { printf(...
(1) Go topythontutor.comand select a language. Here the user chose Java and wrote code to recursively create aLinkedList. (2) Press ‘Visualize’ to run the code. This code ran for 46 steps, where each step is one executed line of code. Go to any step (2a) and see what line of...
