Why you're working on a site and not on Microsoft Visual Stodio?
Could you send me the link for download the MVS?

Hello World!
Tostisto
Guey, how test bit on n position?
Tostisto
If is bit set to 1 or 0
Tostisto
Bit masking (Google it)
#include <stdio.h>
#include <stdlib.h>
#include <stdint.h>
uint8_t stuff() {
uint8_t mask = 0x0f; // 00001111b
uint8_t value = 0x55; // 01010101b
return mask & value;
}
int main(void)
{
stuff();
return 0;
}
Tostisto
Someone help me how do this?
Tostisto
Intput is
Ip: 10.23.110
mask: 255. 255. 192.0
And output is my IP
Please someone help me. Thanks

Can anyone tell which is the best app for drawing and checking flowchart??
KGF
int main()
{
int a = 10;
if (a == a--)
printf("TRUE 1\t");
a = 10;
if (a == --a)
printf("TRUE 2\t");
}
KGF
Can anybody explain this
Roshan
KGF
2 is the output
KGF
But how
!/usr
int main()
{
int a = 10;
if (a == a--)
printf("TRUE 1\t");
a = 10;
if (a == --a)
printf("TRUE 2\t");
}
In first case
It first compares then decrease the value of a
!/usr
But in second case
It first decrease the value of a then compares
Roshan
int main()
{
int a = 10;
if (a == a--)
printf("TRUE 1\t");
a = 10;
if (a == --a)
printf("TRUE 2\t");
}
--a is the prefix operator and
a++ is the postfix.
when you say
cout<<a--;
first the value of a will be printed then a is decremented by 1 i.e. a = a - 1;
Whereas, if you write
cout<<--a;
then a is first decremented then it is printed.
Roshan
int main()
{
int a = 10;
if (a == a--)
printf("TRUE 1\t");
a = 10;
if (a == --a)
printf("TRUE 2\t");
}
Here in your program, you're checking if ( a == a--) printf("TRUE 1\t");
So is a == a ........ which is CORRECT
After this a is decremented
so the output is 1
Roshan
Get it?
olli
int main()
{
int a = 10;
if (a == a--)
printf("TRUE 1\t");
a = 10;
if (a == --a)
printf("TRUE 2\t");
}
it's UB, different compilers produce different results.
Clang issues warning, (GCC does too on -Wall)
<source>:5:19: warning: unsequenced modification and access to 'a' [-Wunsequenced]
if (a == a--)
~ ^
<source>:8:18: warning: unsequenced modification and access to 'a' [-Wunsequenced]
if (a == --a)
~ ^

Well is it that the output will be different... I'm confused

ICC/GCC outputs TRUE 2
Clang outputs TRUE 1

Have to I download Visual studio 2019 or visual studio code ?

Have to I download Visual studio 2019 or visual studio code ?
you can do it even with vi editor or code blocks or sublimetext
Crbala
it is not hard rule to use either vstudio or vscode
Crbala
yes there are static check addons are available indeed in vscode
Crbala
but the usability of these IDE and editor makes a suitable choice for some of engineers
Crbala
I know certain Product devlopment company who used VStudio to the core and they had to live with winmain to translate the calls from linux to windows based one
Crbala
since their entire product code was written with MFC
Crbala
as one of their core package

hi,
can anyone recommend my a way to catch a negative value?
for example if i want to calc with days and months, that 31.10 is lower than 1.11.
or is there a better way to do this?
Mino
as one of their core package
Hence, Do u advice me to use Vscode ? If I will have problem, I'll change it with Vstudio.
Crbala
Crbala
you cna use vscode
Mino
Because with c++ compiler I'm not able to plot the function. Because maybe, I don't have the library
