Cpp1.cpp引用:
#include "stdafx.h"
void shuchu(char * str1,char str2)
{
    printf(str1,str2);
}ceshi.cpp引用:
#include "Cpp1.cpp"
#include "stdafx.h"

int main(int argc, char* argv[])
{
    printf("Hello World!\n");
    shuchu("ceshi1","ceshi2");   
         return 0;
}标红的地方都有问题...

跟这个没关系吧,我试过后依然是这样,

printf(str1,str2);
不能这样用啊...

#include"stdio.h"
#include"string.h"

//void shuchu(char * ,char *);


class string1
{
private:
    char *str1;
public:
    string1(){}
    string1(char *p)
    {
        str1 = p;
    }
    friend string1 operator +(string1 &p1,string1 &p2)
    {      
        char *str3 = strcat(p1.str1, p2.str1);
        return string1(str3);
    }
    void shuchu()
    {
        printf(str1);
    }
};


void main(int argc, char* argv[])
{   
    char test[20] = "test";
    string1 a(test), b("ceshi2"),c;
    printf("Hello World!\n");
    c = a + b;
    c.shuchu();
}
