I ran into a problem.

/*primer2_2*/

/*Pirkaz na ekranu zadatog celog broja u raznim oblicima*/


#include <stdio.h>


main()

{    int x;

     

     printf("\nUnesite ceo broj:\t");

     scanf("%d", &x);

     

     printf("\nDecimalnim oblik:\t%d:",x);

     printf("\nOktalni oblik:\t\t%o",x);

     printf("\nHeksadecimalni oblik:\t%x (%X)\n\n",x,x);

     getchar();

     return(0);

}   

That is a code that i wrote but when i compile it and run it i type a number to see Decimal, Hexadecimal and Octal number of any number that i typed previously but application ends too fast.
Where did i made mistake?
Thnks for Help

This is the goddamn 3rd thread I post about this problem....
In C, I see? Then, nothing wrong, bad compiler :p Which compiler, btw?

Try system("pause") instead of getchar(). That might do it, but getchar() is better.

Thanks it works I use Dev C++ Version 4.9.9.2

[marwex89]

That's not a bad compiler really, but getchar() won't get you there :p

In C++ there are other methods, see the other threads about this..

scanf() isn't catching the newline, which then goes to getchar(). Use fgets() and sscanf():

/*Pirkaz na ekranu zadatog celog broja u raznim oblicima*/

#include <stdio.h>
#include <stdlib.h>
main()
{    int x;
     
     printf("\nUnesite ceo broj:\t");
     char * s = malloc(100);
     fgets(s,100,stdin);
     sscanf(s,"%d", &x);
     free(s);
     
     printf("\nDecimalnim oblik:\t%d:",x);
     printf("\nOktalni oblik:\t\t%o",x);
     printf("\nHeksadecimalni oblik:\t%x (%X)\n\n",x,x);
     getchar();
     return(0);
}

That should work.

Or 2 getchars, etc...
Those input buffers are annoying, IMO..

[Aereshaa]

All you need to do is always use line-by-line input.

[marwex89]

I guess, but it's one of those things I'd rather not have to worry about when making a program, eh? It's sort of fun too, though..

[BINNY88]

type a new header #include<conio.h> & replace getchar() with getch();,it worked well with the modification.

[marwex89]

I think conio is windows only?

[BINNY88]

Nope its not winows only header.Actually its part of ANSI c.getch() works only if this header is present.

[marwex89]

Allright, I wasn't sure :p
