实现一个通讯录；通讯录可以用来存储1000个人的信息，每个人的信息包括：姓名，性别，年龄，电话，住址提供方法：1.添加联系人信息                  2.删除指定联系人信息                  3.查找指定联系人信息                  4.修改指定联系人信息                  5.显示所有联系人信息

1.编写一个函数实现n^k，使用递归实现#include int main(){ int fun(int n,int k); int n; int k; int sum; printf("input n,k:"); scanf("%d,%d",&n,&k); sum=fun(n,k); printf("%d^%d=%d\n",n,k,sum); return 0;}i

1.判断1000~2000之间的闰年。#includeint main(){int year;for (year=1000;year<=2000;year++){ if(year%4==0) { if(year%100==0) { if(year%400==0) printf("%d\n",year); }

1.写一个函数返回参数值为1的个数。# includeint main(){   int a;   int count=0;   scanf("%d",&a);   while(a>0)       {              if(a%2==1)                 count++;           a=a/2;

//50.使用c语言编写函数：unsigned int reverse_bit(unsigned int value);//这个函数的返回值是value的二进制位模式从左到右翻转后的值/*方法一：通过位运算取出25的每一位二进制数，取出第一个数乘以2^31,第二个数乘以2^30，依次取出并计算出总和#include #include #include typedef unsigned

/*10.交换两个整数的值（传址）传值调用不能改变两个变量的值，而传址能；因为，传值调用仅仅是在函数内，调换参数的值，而地址所指向的值，改变的不仅是函数内，函数外也改变。#include void swap(int *x,int *y){ int temp; temp =*x; *x=*y; *y=temp;}int main(){ int x=1; int y=6;
