请教一个关于连接字符串的问题~
用字符数组，不用strcat函数，将两个字符串连接起来

代码如下：

#include <iostream>
using namespace std;

int main()
{
    int i,j;
    char c1[]={"Huizhou "},c2[]={"xueyuan"};
    const int a=strlen(c1),b=strlen(c2);
    const int k=a+b;
    char c3[k];
    
    for(i=0;i<=a-1;i++)
        c3[i]=c1[i];
    for(i=a;i<=a+b-1;i++)
        for(j=1;j>j+1;j++)
            c3[i]=c2[j];
    return 0;
}

编译时出错，求教~谢谢了~
