num=(rand()%3) == 2 ? 2.0 : (rand()%2) + (float)(rand()%1000000)/1000000;

I want to get random float numbers from 0 to 2 (included). How do I do this?

Why is not essential to give the size of the first dimension ---eg. int func (int array [] [20], int x));--- when declaring a two dimensional array as a parameter of a function?

#include <stdio.h>

main(t,_,a)
char *a;
{return!0<t?t<3?main(-79,-13,a+main(-87,1-_,
main(-86, 0, a+1 )+a)):1,t<_?main(t+1, _, a ):3,main ( -94, -27+t, a
)&&t == 2 ?_<13 ?main ( 2, _+1, "%s %d...

If I define


#define array "abcdef"

int main()
{
printf("%c", array[0]);

return 0;

If I use that code is working and compile:


int main()
{
int array[] = {1,2,3,4,5};

printf("%d", array[0]);

return 0;

Hello. I have a problem. I want to define a constant array.


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

#define array[] {'a', 'b', 'c'}


int main()

Perfect thank you

#include <stdio.h>

int main()
{
double a=0;
printf("Give a Float number (ex. 346.58)");
scanf("%e", &a);

printf("\n\n---->%lf\n\n", a);

GCC Compiler.

I use two kind: FreeBSD and Fedora

With %le the result is 5.609771e-315.


But I want 346.58.

Hello again. I have problem with double printing.



#include <stdio.h>

int main()
{
double a=0;

Perfect Thank you

Thank you very much.
But if I print

printf("\n\n%f\n\n", k);

the result is 1.5899. How I disable round in printf?

Hello to everyone, I have a small problem.

My example code:



#include <stdio.h>

int main()
{

I im reading Williams Stalling book for operating systems and he use semaphores , monitors and message passing. I just want to see real c code of monitors example.

Thank you.

Hi. How can I write a monitor form my multithret program? Where I can find examples for c?

Thank in advance

Any other way. Some dll or library that I can use? And some good documentation that I can start form with a simple tutorial?

Any one who knows how to use cygwin dll to write a cd burning software?

Where I can find tutorials or documentation?

What Libraries, sdks I need to write a cd burning software?

linux. bmp

type x = (type *) malloc(sizeof(type));

sizeof(type) counts the size of the variable for example


(int*)malloc(sizeof(int))

get 4bytes mem

#include <stdio.h>

int main (){
int counter;
int counter2;

system("clear"); //clear the consol
for (counter=1; counter < 6; counter++){
printf("| ");
for(counter2=1;...

I want to write with c a picture viewer what libraries I will need?
