Thread: help me. i have 3 error.

* Fix your indenting, you're probably missing a bracket.
* Avoid using conio.h and getch().

Then your errors will disappear, or at least you'll be able to see them

why. avoid using getch. huhuhu help me please.

Because it's not portable.

Stop spamming the same question, starting new threads etc -- it's obvious this is an assignment. Fix your indenting then we'll work from there.

This is what your code should look like in your code editor, and what it should look like posted on a forum.

Code:

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

char *str, select;

main()
{
    int item;
    do {
        clrscr();
        printf("1. FACTORIAL\n");
        printf("2. FIBONACCI\n");
        printf("3. EUCLID\n");
        printf("4. EXIT\n");
        printf("SELECT AN OPTION:\n");
        scanf("%d", &item);
        if (item == 1) {
            clrscr();
            {
                long a, b, c;
                gotoxy(1, 1);
                printf("RECURSIVE\n");
                printf("Enter a Number: ");
                scanf("%li", &a);
                c = 1;
                b = 1;
                do {
                    printf("%li = %li*%li=%li\n", b, b, c, b * c);
                    c *= b;
                    b++;
                } while (b <= a);
                printf("FACTORIAL IS %li", c);
            }
            getch();
        } else if (item == 2) {
            clrscr();
            {

                a = 1;
                if (c < 1)
                    printf("TRY AGAIN");
                else
                    printf("0\t");
                for (ctr = 1; ctr <= c; ctr++) {
                    printf("%d\t", f);
                    if (ctr > 1) {
                        b = f + a;
                        a = f;

If it doesn't, then work on that until you get it right. You've had 50 posts now, it's time you learnt this basic stuff.

I've added a couple of comments to indicate where the braces are screwed up.
