This program is a simple guessing game. The computer is to generate a random
number between 1 and 20. The user is given up to five tries to guess the exact number. After each guess, you are to tell the users if the guessed number is greater than, less than, or equal to the random number. If it is equal, no more guesses should be made. If the user hasn't guessed the number after five tries, display the number with a message that the user should know it by now and terminate the game.
Your design for this program should include a separate function to get the user's guess, a function to print the unsuccessful message, one to print the successful message, and one to print the sorry message.

No while. Only using if else statemet.

A Possible successful dialog:
I am thinking of a number between 1 and 20.
Can you guess what it is? 10
your guess is low. Try again: 15
Your guess is low. Try again: 17
Your guess is high. Try again: 16
Congratulations! You did it.

A possible unsuccessful dialog:
I am thinking of a number between 1 and 20.
Can you guess what it is? 10
Your guess is low. Try again: 20
Your guess is high. Try again: 10
Your guess is low. Try again: 18
Your guess is high. Try again: 12
Sorry. The number was 15.
You should have gotten it by now.
Better luck next time.

This program needs to be written in C.

This is what I have so far but i cant get it to compile. It gives me all kinds of read errors.

#include <stdio.h>
#include <conio.h>
#include <stdlib.h>
int getnumber();
void unsuccessful(int);
void successful();
void sorry(int);
int main()
{int randomnumber,number=-1,count=5;
srand(time(0));
randomnumber=(rand()%20)+1;
printf("I am thinking of a number between 1 and 20.\nCan you guess what it is? ");
while(randomnumber !=number)
     {
      number=getnumber();
        if(number==randomnumber)
            {successful();
            getch();
            return 0;
            }
        else
           if(count==1)
              {
              sorry(randomnumber);
              getch();
              return 0;
              }
           if(number<randomnumber)
          unsuccessful(1);
       else
          unsuccessful(0);
      count--;  
    }


}
void sorry(int n)
{
printf("Sorry. The number was %d.\nYou should have gotten it by now.\n",n);
printf("Better luck next time.");
}
int getnumber()
{int number;
scanf("%d",&number);
return number;
}
void unsuccessful(int n)
{if(n==1)
      printf("Your guess is low. Try again: ");
else
     printf("Your guess is high. Try again: ");
}
void successful()
{printf("Congratulations! You did it.\n");
