hi  , I   am 36

适合对象c语言初学者

strcat(arr1,arr2); 是使arr2的内容接到arr1

格式

#include<string.h>

strcat(arr1,arr2)

arr2首元素会从arr1中的‘\0’开始替换。

返回值为arr1.(即arr1数组的首地址)链接分享一下arr的意义(c基础)-CSDN博客​​​​​​

#include<stdio.h>
#include<string.h>//strcat(arr1,arr2) 接  string
int main()
{char arr1[100] = "hi ,";char arr2[] = "I am 36";//返回值arr1printf("%s\n", strcat(arr1, arr2));printf("%s", arr1);return 0;
}
