strcpy(字符串拷贝)
#include <stdio.h>
#include<string.h>
int main(){
char string[10];
char *str="fsdfsdg";
strcpy(string,str);//将参数str字符串拷贝至参数dest所指的地址
printf("%s\n",string);
}
strcat(字符串拼接)
#include <stdio.h>
#include<string.h>
int main(){
char destination[25];
char *blank=" ",*c="C++",*Borland1="Borland";
strcpy(destination,Borland1);
strcat(destination,blank);
strcat(destination,c);
printf("%s\n",destination);
}
strcmp(字符串比较)
#include <stdio.h>
#include<string.h>
int main(){
char *a="asdfghjk";
char *b="ASDFGHJK";
char *c="azsdfghj";
char *d="asdfghjk";
printf("%d\n",strcmp(a,b));//根据ASCII码比较,若参数相同返回0,大于返回1,小于返回-1
printf("%d\n",strcmp(a,c));
printf("%d\n",strcmp(a,d));
}
strlen(计算指定字符串的长度,不包括结束字符‘\0’)
