Combine 2 strings

#include <iostream>
#include <time.h>
#include <stdio.h>
using namespace std;

int main()
{
FILE *t;
char PATH[256];
strcpy(PATH,  "c:/");
strcat(PATH, ctime(time()));
strcat(PATH, ".txt");
t=fopen(PATH,"r"); // this could cause problems: "rt" would be preferred
fclose(t);  // change here
return 0;
}

ctime takes time_t as argument, not time_t*.

probably logical error: you're opening a file for reading that will most likely not exist.
