I tried to create a strcat function, but it didn't work, so I'm asking you a question.

#include <stdio.h>
#include <string.h>

char* mystrcat(char* pszDst, char* pszSrc)
{


    while (*pszDst != '\0');
    ++pszDst;
    while (*pszSrc != '\0')
        *pszDst++ = *pszSrc++;

    *++pszDst = '\0';

    return --pszDst;


}
int main() {
    char szPath[128] = { 0 };
    char* pszEnd = NULL;

    pszEnd = mystrcat(szPath, "C:\\Program Files\\");
    pszEnd = mystrcat(pszEnd, "CHS:\\");
    pszEnd = mystrcat(pszEnd, "C programming");

    puts(szPath);
    return 0;


}
