Thread: random functions

The following code has two random functions that don't pick random. THEY ALLWAYS PICK 0!!!!can anyone help me???

<near the bottem>



#include <iostream.h>
#include <conio.h>
#include <stdlib.h>
int main()

cin>>plyrs;
if (plyrs==2)

cout<<"please enter amount o' tries: "<<endl;
cin>>tries;
clrscr();
cout<<"hider, type coordinates of hidden character:<has to be under 10,10 please."<<endl;
cin>>x>>y;
clrscr();
cout<<"seeker, you are at coordinates 0,0. you will have to find the hidden character in 15 tries. move up down left and right. good luck."<<endl;
getch();

int c = 0;

Please help me if you can!!!
