自写字符串连接函数strcat

#include<stdio.h>
#define STRLEN 100
char *mystrcat(char *dest,const char *src)
{
	char *ret = dest;
	while(*dest != '\0')
	{
		dest++;
	}
	while(*dest++ = *src++)
	{
		;
	}
	return ret;
}

int main()
{
	char dest[STRLEN] = "andef";
	char *src = "ghi";
	printf("%s\n",mystrcat(dest,src));
	return 0;
}
