You mean if I use fgets in stead of scanf ?

I think you don't understand my question at all :p

Yes I know and yes I did search for how 2 use fgets, but I didn't gbet anything.

My wone code?


int x = 0;

scanf("%d",&x);
printf("Root of %d is %d",x,sqrt(x));

Yes, but how to use it, pleas? and with wich library ?

Thank you

Hi,


scanf("%d",&x);

How can I control the input ?


if (x is a number) {
//do this

Thank you all for your replies .. I am learling both languages: C and Java :D .. but the pointers in C are making me crazy :cool: :D

I'm doing 2 courses: first course = 120 hours of Java and if I...

If I have this :

scanf("%d",&x);
scanf("%d",&x);
scanf("%d",&x);

printf("%d",x);
You said so this means I have to use getChar() three times to see the output !!!?

BUT, suppose I have this program:

#include <stdio.h>
int main(void) {
int x;
scanf("&#37;d",&x);
printf("You entred %d",x);
return 0;
} I muy enter \n 'enter keys' as much as I...

Yesss .. it works .. thank youuu (f) this is much better caus I can't know when or where the program leavs charachters .. !!

Thanks, I get it ..

while(getchar() != '\n') {}
getchar(); Do I really need this for eating the characters left by printf and scanf functions?

:eek: :mad: :rolleyes: :devil: :confused:
I don't understandddd ...

You are talking about the function scanf () which leaves according to you a newline dangling in the input buffer !!!


BUT

Mmm so Getchar() waits for keypress, O.K .. I get it but why do I have to add it ?? why do my program stop if I don't add Getchar() ???


Normally it has to process untill if arrives at }

Yes Dev-C++ :) .. I'm gonne read it but now I have another Q:


#include <stdio.h>

int main(int argc, char *argv[])
{
int a[10];
int i, j, temp;
printf("Give me 10 integers:\n");

I don't understand the differences, I installed Div C++ and I got another code for hello world app:


int main(int argc, char *argv[])
{
printf("Hello World!\n");

printf("Press ENTER to...

Hi,
I'm new in the world of programming, I just begun to program in C langauage.. I started to write my first program using Borland C++ and I can use different styles :

@Elysia

Yes, I was reading today in a book about differences between C and Java and I read about pointers in C using stars but there is no pointer in Java.

The Question is: no pointers in Java...

Thank you, .. do you do that ? you are programming on a very low layer if you operate the memory .. you can program virus with C :D

I think it's a lot work to do this memory...

Can you pleas give me an example? but in C we don't have objects !! or not ?

Elysia,
No, I don't want emulators => that's too technical ... I just want in the future to make programs processing...

I don't know that, that is why I ask in this topic.

Yes, in Java there is applet like this: http://www.physics.uoguelph.ca/applets/Intro_physics/kisalev/java/resist2/index.html

Thank you all for your responses, I really appreciate that.
