#define _CRT_SECURE_NO_WARNINGS#include<stdio.h>int main(){ int a = 10; int* p = &a; //指针变量用 int*,char*等来表示 printf("%p\n",p); //打印指针用%p printf("%p\n",&a); //&为取地址符号 *p = 22; //*号为地址解析符号,此处*p = a; printf("%d\n",a); return 0

自定义函数#include <stdio.h>void seeHello();//自定义函数声明int main(){ printf("How are you!\n"); seeHello();//函数调用 printf("me too,I'am fine!\n"); return 0;}//函数定义void seeHello(void){ printf("I'am fine,and you!\n");}...

C语言 while循环的应用int main(){ //int ch = 20; //printf("%d\n",ch); int a=1; int b; while(a<=5){ b=1; while(b<=a){ printf("*"); b = b + 1; } printf("\n"); a = a + 1; } return 0;/*输出内容如下：****************/}...
