plz tell me where the error lies!

Code:

---


#include<stdio.h>
#include<stdlib.h>
#include<time.h>
#include <conio.h>








int main(void)
{
    int num;
    int randnum;
    int tries;


   
    char choice = 'y';
   
   


    randnum = 1 + rand() % 1000;
    tries = 1;


    printf("I have a number between 1 and 1000.\n");
    printf("Can you guess it?\n");
    printf("Please type your guess: ");
    scanf("%d", &num);
    printf("\n\n");


    do {   
          while(num != randnum)
          {
              if(num < randnum)
              {
                    printf("Too low. Try again.\n\n");
                    printf("Next guess:\t ");
                   
                    scanf("%d", &num);
                    printf("\n");
              }


              if(num > randnum)
              {
                    printf("Too high. Try again.\n");
                    printf("Next guess: \t");
                 
                    scanf("%d", &num);
                    printf("\n"); }


              tries ++;}
               
              if(num == randnum)
              {
                printf("Excellent! You guessed the number with %d tries!\n\n", tries );
                                       
                printf("Would you like to play again (y or n)? ");
                scanf("%c", &choice);}}
    while(choice == 'y');
               


    getchar();


    return 0;
    }

ANOTHER OPTION I AM TRYING IS TO USE goto

Code:

---

if (choice == 'y') {
goto loop; }

---

where loop is at the begging of the code

Your spacing and placement of braces is terrible. Fix that and someone might help you, or you may even see your own mistake.

Also, don't just say "error in code", say exactly what's going wrong: what do you expect it to do, what does it actually do?

And don't use a goto.

By definition, setting choice to 'y' before the loop is unnecessary, as a do-while loop will always execute the body at least once, and then continue based on the condition.

You should also fix the newline character buffering issue, your scanf() calls never deal with the '\n' left in the input buffer, and you don't fix this with subsequent getchar() calls like you should.

Fix these issues, and fix the indentation.
