- 打印字符串:%s--------printf(“%s”,”abcd”);
- 打印字符串数组中某一位:%c--------printf(“%c”,”abcd[2]”);
- 字符的定义及打印格式:
struct { int amount; char *name; }coins[] = { {1,"one"}, {2,"two"}, {3,"three"} }; char *abc="zxcvbnm"; printf("%s\n",coins[2].name); printf("%s",abc);
- 字符串数组初始化;
char s1[]="array"; //字符数组 char s2[6]="array"; //数组长度=字符串长度+1,因为字符串末尾会自动添‘\0‘ printf("%s,%c\n",s1,s2[2]); //array,r
- 字符串指针初始化;
char *sp="pointer"; //字符指针 printf("%s,%c,%c\n",sp,*sp,*(sp+2)); //pointer,p,i
- 数组+scanf
char s1[6]; scanf("%s\n",s1); printf("%s,%c\n",s1,s1[2]); //array,r
- 指针+数组+scanf
char str[60], *sp=str;//将数组的首地址str赋给指针变量sp scanf("%s\n",sp); printf("%s,%c,%c\n",sp,*sp,*(sp+3));//pointer,p,n printf("%s,%c,%c\n",str,str[0],str[3]);//pointer,p,n
- 使用scanf对结构体进行赋值;
#include<stdio.h> struct student { int num; char name[10]; }; void main() { struct student s; printf("输入学号:\n"); scanf("%d",&s.num);//scanf赋值给结构体的num成员 printf("输入姓名:\n"); scanf("%s",&s.name); printf("输入的信息为:学号:%d,姓名:%s\n",s.num ,s.name); }
- 输入数据语句的格式:scanf(“%d”,&x);
- char*:字符指针类型
