以下是使用C语言编写的程序，用于生成由1、2、3、4、5组成的数字不重复的3位整数，并输出这些整数及其个数：include <stdio.h> int main() { int count = 0; // 计数器，用于统计整数的数量 for (int i = 1; i <= 5; i++) { for (int j = 1; j <= 5; j++) { if (j =...
组成的个数是： P(3, 5) = 5 * 4 * 3 = 60个;下面是程序：include <stdio.h> int main(void){ int i, j, k;int count = 0;for (i=1; i<=5; i++) { for (j=1; j<=5; j++) { if (j != i) { for(k=1; k<=5; k++) { if(k!=i && k!=j) { count...
include<stdio.h> void main(){ float i,sum=0;int n;scanf("%d",&n);for(i=1;i<=n;i++)sum+=i/(i+1);printf("sum=%f\n",sum);}
if(!(n%i)) return 0; return 1;}int main(void){ char a[6]={1,2,3,4,5,6},i,j,k; k=i=0; while(1){ j = i<5 ? i+1 : 0; if(!prime(a[i]+a[j])){ k=a[j]; a[j]=a[0]...

写了一个，请参考。include<stdio.h> int main(){ int a[3][3]={1,2,3,4,5,6,7,8,9};int i = 0, j = 0, sum = 0;for(i = 0; i < 3; i++){ sum = 0;for(j = 0; j < 3; j++){ sum += a[i][j];} printf("第%d行的和：%d\n", i, sum);} retu...
