Continuous loop or counter problem or both?

I have coded a "guess the number" program. When the user inputs his guess, the program is supposed to tell him: "Excellent! Would you like to play again (y or n)?" or "Too Low. Try again." or "Too High. Try again.". The user is supposed to have 6 guesses before the game ends. My problem is that the program gives him one chance to enter a guess and then gives outputs all of the choices . I am not sure how to fix my program or where the error(s) are within the program.

Code:

#include <iostream>
using std::cout;
using std::cin;
using std::endl;

#include <cstdio> 

#include <cstdlib> 

#include <ctime> 

int randomNumber(); 
void test(int yourGuess, int rnum); 
void intro(); 

void main(void) 
{ 

int i=0; 

int rnum=0; 

int yourGuess = 0; 

int count = 0;

long ltime = time(NULL); 

unsigned stime = (unsigned)(ltime/2); 


intro(); 

cin >> yourGuess; 

srand( time( 0 )); 

for (i=0; i<6; i++) 
{ 
rnum=randomNumber(); 
test( yourGuess, rnum);
}


return; 
} 

void intro(void) 
{ 
cout << "I have a number between 1 and 1000.\n"; 
cout <<  "Can you guess my number?\n"; 
cout <<  "Please type your first guess.\n"; 
 
} 

int randomNumber() 
{ 
int number =-99999; 

number= 1 + rand() % 1000; 

return number; 
} 

void test(int yourGuess, int rnum) 
{ 

if ( yourGuess < rnum )
	cout << "Too Low. Try again" << endl;

else if ( yourGuess > rnum )
	cout << "Too High. Try again" << endl;

if ( yourGuess = rnum )
	cout << "EXCELLENT! You guessed the number!\n";
	cout << "Would you like to play again (y or n)?" << endl;


	    

}

I would appreciate it if someone could please point me to where in my program that my error(s) are so that I can try to fix them. Sorry to post the whole code but since I am not sure where the problem is I thought it might be needed.

You read "yourGuess" only once.

> void main(void)
main returns an int

Learn the magic of indenting code to make your intentions more obvious.

> rnum=randomNumber();
Changing the number every guess is a bit mean don't you think?
The whole point of too high / too low is to home in on the actual result.

> if ( yourGuess = rnum )
It's == for comparison.
Turn up the warning level of your compiler.

Besides, your random number is not "between 1 and 1000" as advertised, but between 0 and 999, courtesy of the % operator.

Also, it's quite impossible to guess the number correctly in 6 guesses. Perhaps you want to replace "6" with "10".

Here's a hint: instead of asking the COMPUTER to guess the USER's number, try making the USER guess the COMPUTER's number
