Thread: Guess the number game

Hi there

Fairly new to programming and c, I decide to make a guess number game but I'm having some trouble with it, the random number is always 0 when the user guesses the right number and then chooses to play again, if the user selects 2 to exit it won't exit the program, here's my code, any help appreciated.

Code:

#include <stdio.h>#include <stdlib.h>
#include <time.h>
#include <stdbool.h>
void headerMessage();
void getGuess(bool,int,int);
void outOfBounds(int);
void tooLow();
void tooHigh();
void guessNumber();
void guessesLeft();
void checkGuessAttempts();
void playAgain();
void outOfBounds2();
void goodBye();


static int selectedNumber;
static int userNumber;
static bool gameOver = false;
static bool keepGoing = true;
static int playagain;
static int const MAX_GUESS_ATTEMPTS = 5;
static int nTries = 0;
static int nTriesLeft = 5;


int main()
{
    srand(time(NULL));


    headerMessage();
    getGuess(gameOver,userNumber,selectedNumber);


    return 0;
}


void headerMessage(){
    printf("\n********************");
    printf("\n*   Guess The      *");
    printf("\n*   Number Game    *");
    printf("\n********************");
}


void getGuess(bool gameOver,int userNumber,int selectedNumber){
    do{
       //selectedNumber = rand()%20+1;
       printf("\n%d" , selectedNumber);
       printf("\nGuess a number between 1 and 20: ");
       scanf("%d", &userNumber);
       outOfBounds(userNumber);




    }while(gameOver == false);
}


void outOfBounds(int userNumber){
    if(userNumber < 0 || userNumber > 20){
        printf("NUMBER ENTERED OUT OF BOUNDS! ");
    }
    else{
        guessNumber(userNumber);
    }
}


void tooLow(){
    printf("TOO LOW! TRY AGAIN!");
}


void tooHigh(){
    printf("TOO HIGH! TRY AGAIN! ");
}


void guessNumber(int userNumber){
    if(userNumber < selectedNumber){
        tooLow();
        nTries++;
        nTriesLeft--;
        guessesLeft();
    }
    else if(userNumber > selectedNumber){
        tooHigh();
        nTries++;
        nTriesLeft--;
        guessesLeft();
    }
    else{
         printf("You got it! press 1 to play again or 2 to quit: ");
         printf("It took you %d ", nTries);
         scanf("%d", &playagain);
         nTriesLeft = 5;
         nTries = 0;
         playAgain();
    }
    checkGuessAttempts();
}


void guessesLeft(){
    printf("You have %d ", nTriesLeft );
}


void checkGuessAttempts(){
    if(nTries >= MAX_GUESS_ATTEMPTS){
        printf("GAME OVER! ");
        gameOver = true;
    }
}


void playAgain(){
    while(playagain !=1 && playagain !=2){
        outOfBounds2();
        scanf("%d", &playagain);
    }
    if(playagain == 2){
        gameOver = true;
        goodBye();
    }
    else{
        selectedNumber = rand()%20+1;
    }


}


void outOfBounds2(){
    if(playagain < 1 || playagain > 2){
        printf("OUT OF BOUNDS CHOICE, ONLY SELECT OPTION 1 OR 2! ");
    }
}


void goodBye(){
    printf("Goodbye! ");
}
