Problems with this thing?

Code:

---

#include <iostream>
#include <fstream>
#include <math.h>
#include <time.h>
using namespace std;
#define MAX 256
FILE *f;
ofstream VB;
char I;int x,k;char p;
int main(){
x=time(NULL);
srand(x);
k=rand()%1000+1;                        strcpy(p,k);  // variable 'k' holds the random number, p holds nothing.
char PATH[MAX];
strcpy(PATH,"c:/");
strcat(PATH,p);
strcat(PATH,".txt");

VB.open(PATH);
VB<<k;
VB.close();
cout<<PATH<<endl;
cout<<x<<endl;
cout<<k<<endl;

system("pause");
x=NULL;k=NULL;
        return 0;
}

---

I don't know why I cannot convert char to const char. See it for yourself.

What are you talking about? Strcpy() won't work because both parameters have to be C strings (char[]). You can't use it with an int and a char.

Can u try to help me out?

Yes, but only if you promise to indent, format, and otherwise make readable your code from now on ;)

Code:

---

#include <iostream>
#include <fstream>
using namespace std;
#include <cstdlib>

#define MAX 256

int main()
{
    // Declare variables
    ofstream VB;
    char I;
    int x, k;
    char p[10], PATH[MAX];

    srand(time(NULL)); // Initialize random number generator
    k = (rand() % 1000) + 1; // Assign k a random number from 1 to 1000
    itoa(k, p, 10); // Convert k to a C string and store it in p

    // Create path
    strcpy(PATH,"c:/");
    strcat(PATH,p);
    strcat(PATH,".txt");

    // Write number to file
    VB.open(PATH);
    VB<<k;
    VB.close();

    //Print out numbers
    cout<<PATH<<endl;
    cout<<x<<endl;
    cout<<k<<endl;

    // End
    system("pause");
    return 0;
}

I would like to get Randomized Numbers without using
time(NULL);

As an alternative to itoa(), you can use sprintf:

Code:

---

sprintf(PATH, "c:\\%i.txt", k);

srand(time(NULL)) initializes the random number generator. If you do not write this (you don't have to) your random numbers will always start at the same point.

What library is sprintf() in?

stdio.h
