c语言使用指针实现模拟java/c# string.concat字符串串联方法

#include <stdio.h>
void _strcat(char *, const char *);

int main(void)
{
    char source[] ="View";
    char dest[] ="GoldenGolbal";
    _strcat(dest,source);
    printf("%s\n",dest);
}
//append string from source to dest
void _strcat(char * dest, const char * source)
{
    int j,i=0;
    
    while(dest[i] != ‘\0‘)
    {
        i++;
        j = i;
    }

    i = 0;
    while(source[i] != ‘\0‘)
    {
        dest[j+i] =source[i];
        i++;
    }
}
