模拟实现strcat

#include<stdio.h>#include<stdlib.h>#include<Windows.h>#include<string.h>#include<assert.h>char *my_strcat(char *dest,char *src){char *ret = dest;assert(dest);assert(src);while(*dest){dest++;}while(*dest++ = *src++){;}return ret;}int main(){    char arr1[15]="abcd";    char *arr2="ef";    printf("%s\n",my_strcat(arr1,arr2));system("pause");return 0;}
