C语言编程:输入一个数判断是否为素数(质数),输出判断结果信息(prime number素数). 答案 #include "stdio.h"#include "math.h"main(){int i,n,flag=1;printf("Please Input a number:");scanf("%d",&n);for (i=2;i相关推荐 1C语言编程:输入一个数判断是否为素数(质数),输出判断结果信息(prime number素...
素数又叫质数(prime number),有无限个。质数定义为在大于1的自然数中,除了1和它本身以外不再有其他因数。 二、代码实现 1.主函数构建 代码语言:javascript 代码运行次数:0 AI代码解释 intmain(){int n=0;int count=0;printf("请输入一个整数n:");scanf("%d",&n);printf("从%d到%d的范围内所有的素数:...
intm, n, i, prime; i = 0; for(m = 2; m <= 100; m ++) { prime = 1;/*设定一个标志,先假定是素数*/ for(n = 2; n < m; n ++) if(m % n == 0) prime = 0;/*表明 m 不是素数*/ if(prime)/*是素数*/ { printf("%6d", m); i ++; if(i % 5 == 0) printf(...

, n); else printf("%d is not a prime number.", n); return 0; } Run Code Output Enter a positive integer: 29 29 is a prime number. In the program, a for loop is iterated from i = 2 to i < n/2. In each iteration, whether n is perfectly divisible by i is checked ...
7. Prime Check Function Variants Write a program in C to check whether a number is a prime number or not using the function. Pictorial Presentation: Sample Solution: C Code: #include<stdio.h>intPrimeOrNot(int);intmain(){intn1,prime;printf("\n\n Function : check whether a number is ...
