not sure why when i press n the function doesn\'t break, but if ipress y it work

Question

not sure why when i press n the function doesn't break, but if ipress y it works going to the next function.
this my code, if you can spot the problem it would be helpful byshowing the code:

#include <iostream>
#include <cstdlib>
#include <ctime>

using namespace std;

/*
* Prototypes ---place the prototypes for your user definedfunctions here
*/
//free function....
char yesNo();
int getUserNumber();
int getRandomNumber();
int random_number;



int main(int argc, char *argv[]){

//your main will have a repeating loop that gets the user to playthe guessing game as many times as they like.

//there will be function calls to get the random number, and to getthe user to enter a number.

cout << " ***Guessing Game***" <<endl<<endl;

getUserNumber();
        
system("PAUSE");
}



//Down here you will define your 2 functions, more if you see otherparts suitable for functions



//This is your free function. It gets the Y or N characterfrom the user and returns it
char yesNo()
{
char result;
bool valid=false;

while (valid==false){
       //user will be forced to entera letter until they give a valid one
       cout<<"Do you want toplay again? (Y/y or N/n) ";
       cin>>result;
       //check to see if it is avalid choice
       if ((result=='y') ||(result=='Y')){
          cout<< endl; valid = true;
         getUserNumber();}
        
       else if ((result=='n') ||(result=='N')){
           cout << endl <<endl << "Thanks for playing!"<<endl; break;}
       else
          cout<<"You have to type a valid character.... Tryagain"<<endl;
}//end while

//sends the valid character back
return result;
}//end yesNo


int getRandomNumber(){
  
    const long MAX = 100, MIN = 1;
    srand(time(NULL));
    random_number = (rand() % (MAX - MIN + 1)) +MIN;
  
}
  
int getUserNumber(){
  
    int num, guesses=1;
    getRandomNumber();
    while(num != random_number, guesses++){
          cout<< "Enter an integer number (1-100): ";
          cin >>num;
          cout<<endl;
          if (num <1 || num > 100){
                 cout << "The number must be from 1 to 100! Try again..."<<endl <<endl;}       
          else {
              if (random_number > num)
                 cout << "Guess is too small!" <<endl <<endl;
                 else if (random_number < num)
                 cout << "Guess is too big!" <<endl <<endl;
                 else if (random_number = num){
                 cout << "You guessed it! It took you ";
                 guesses = guesses - 1;
                 cout << guesses;
                 cout << " guesses" <<endl <<endl;
                 yesNo();}
                 
}}}

Explanation / Answer

please rate - thanks It works now, value from yesNo was never returned and checked and afew other minor changes. compare the 2 sets of code #include #include #include using namespace std; /* * Prototypes ---place the prototypes for your user definedfunctions here */ //free function.... bool yesNo(); void getUserNumber(); int getRandomNumber(); int random_number; int main(int argc, char *argv[]){ //your main will have a repeating loop that gets the user to playthe guessing game as many times as they like. //there will be function calls to get the random number, and to getthe user to enter a number. cout
