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...
if(prime)/*是素数*/ { printf("%6d", m); i ++; if(i % 5 == 0) printf("\n"); } } if(i % 5 != 0) printf("\n"); } 运行结果: 第二种采用筛选法来求素数: 使用筛选法求素数的基本思想是:把某一范围内的正整数按从小到大的顺序排列,宣布 1 不是素数,把它筛掉。然后从剩下的...
