C Programming Guessing Game - c

Question

I need help finishing my program. I can't seem to get the last step, when the user enters 'y' to play another game it should start again. If the user enters 'n' then it should end. Thank you in advance for any help. Below is the code I have so far.
Here is the problem:
Write a C program that plays a number guessing game with the user.
Below is the sample run:
OK, I am thinking of a number. Try to guess it.
Your guess? 50
Too high!
Your guess? 250
Illegal guess. Your guess must be between 1 and 200.
Try again. Your guess? 30
**** CORRECT ****
Want to play again? y
Ok, I am thinking of a number. Try to guess it.
Your guess? 58
**** CORRECT ***
Want to play again? n
Goodbye, It was fun. Play again soon.
Code:
#include <stdio.h>
#include <stdlib.h>
#include <time.h>
int main() {
int i, number, currentGuess, MAX_GUESS = 5;
int answer = 'n';
time_t t;
srand((unsigned) time(&t));
number = rand() % 200 + 1;
printf("Welcome to the game of Guess It! \nI will choose a number between 1 and 200. \nYou will try to guess that number.");
printf("If you guess wrong, I will tell you if you guessed too high or too low. \nYou have 5 tries to get the number. \n");
printf("\nOK, I am thinking of a number. Try to guess it. \n");
for (i = 0; i < MAX_GUESS; i++) {
printf("\nYour guess?");
scanf("%i", &currentGuess);
if (currentGuess > 200) {
printf("Illegal guess. Your guess must be between 1 and 200.\n");
printf("Try again.\n ");
}
else if (currentGuess > number) {
printf("Too high!\n");
}
else if (currentGuess < number) {
printf("Too low!\n");
}
else {
printf("****CORRECT****\n");
return 0;
}
}
printf("Sorry you have entered the maximum number of tries. \n");
printf("Want to play again? \n");
scanf("%i", &answer);
if(answer == 'n') {
printf("Goodbye, it was fun. Play again soon.\n");
return 0;
}
else if (answer != 'n') {
printf("Ok, I am thinking of a number. Try to guess it.\n");
}
}

Answer 1

Here's an idea for you to do this in your code:
char answer = 'y';
do
{
// ...
printf( "Want to play again (y/n)? " );
scanf( " %c", &answer );
// Mind ^ the space here to discard any
// previously read newline character
} while ( answer == 'y' );

Answer 2

Check the below code, you might wanna understand the code, rather than just copy pasting it.
The code delegates the task of doing a repetitive task to a function.
The code then relies on the function to say how many chances player has played, or -1 for successful.
And note the getchar() rather than scanf.
NOTE: The extra getchar() is needed, because I don't know but taking character input after taking integer input puts a '\n' character in the stdin, which results in unwanted behaviour. So this is a small trick I always use to tackle such cases.
Pay attention to the do while loop, this case becomes a classic example where you should use do while loop.
Also I have used macros to define MAX_GUESS. That's a good practice. You might wanna google it for "why?"
If you have any further queries, do comment in the answer.
#include <stdio.h>
#include <stdlib.h>
#include <time.h>
#include <ctype.h>
#define MAX_GUESS 5
int playGame(int number)
{
printf("\nOK, I am thinking of a number. Try to guess it. \n");
int i, currentGuess;
for (i=0; i<MAX_GUESS; i++){
printf("\nYour guess?: ");
scanf("%i", &currentGuess);
if (currentGuess > 200) {
printf("Illegal guess. Your guess must be between 1 and 200.\n");
printf("Try again.\n ");
}
else if (currentGuess > number) {
printf("Too high!\n");
}
else if (currentGuess < number) {
printf("Too low!\n");
}
else {
printf("****CORRECT****\n");
return 0;
}
}
return i;
}
int main() {
int i, number, x;
char answer = 'n';
time_t t;
srand((unsigned)time(&t));
printf("Welcome to the game of Guess It! \nI will choose a number between 1 and 200. \nYou will try to guess that number.");
printf("If you guess wrong, I will tell you if you guessed too high or too low. \nYou have 5 tries to get the number. \n");
do
{
number = rand()%200+1;
x = playGame(number);
if (x == MAX_GUESS)
printf("Sorry you have entered the maximum number of tries. \n");
printf("Want to play again? \n");
// To flush the newline character
getchar();
answer = getchar();
} while (answer != 'n' || answer != 'N');
printf("Goodbye, it was fun. Play again soon.\n");
return 0;
