应用指针，编写字符串联接处理函数问题
小弟刚学c++ 希望各位大哥能帮忙写个字符串联接处理函数

[解决办法]



char * __cdecl strcat (
char * dst,
const char * src
)
{
char * cp = dst;

while( *cp )
cp++; /* find end of dst */

while( *cp++ = *src++ ) ; /* Copy src to end of dst */

return( dst ); /* return dst */

}
[解决办法]
#include <iostream>
#include <string>
using namespace std;

char* __strcat(char* src, const char* des) {
char* tmp;
char* ret;

tmp = (char*)malloc(strlen(src) + strlen(des) + 1);
ret = tmp;
while(*src)
{
*tmp = *src;
tmp++;
src++;
}
while(*des)
{
*tmp = *des;
tmp++;
des++;
}

free(src);
src = ret;

return ret;
}

int main()
{
char* p= "your ";
char* q= "hello ";
cout < < __strcat(p,q);
system( "PAUSE ");
return 1;
}
