How to ignore warnings - finding the actual warning / error - android-studio

How can I ignore a Warning / Error in Android Studio?
Like the following, I can see the warning saying:
"warning: The left operand can't be null, so the right operand is never executed."
Now I can see from this and this, that I can do:
// ignore: unused_field
But how do I know the error / warning type from the warning.

Android Studio Flutter Failure with Gradle Exception

I am running this on macOS 10.15.5 Catalina. I recently was able to run this application within the quemu e86 emulator, but recently I have been having issues and now I get odd Gradle errors.
I will preface this by stating that my flutter is completely fubar'd and no matter how many times I add the path to my .bash_profile I am not able to run flutter doctor or anything related to flutter within terminal. Trust me, I have looked through numerous other articles to try to figure this out but thus far I've had no luck.

There may be an error in your flutter cache. run these in your terminal and see if they can help you:
flutter pub cache repair
flutter clean

File not compiling due to syntax error on ';' (semi-colon) [closed]

It's difficult to tell what is being asked here. This question is ambiguous, vague, incomplete, overly broad, or rhetorical and cannot be reasonably answered in its current form. For help clarifying this question so that it can be reopened, visit the help center.
Closed 10 years ago.
My Visual Studio 2010 does not allow my file to be compiled when I use the semi-colon characters (";")/ It says there is an error.
But not all of the semi-colons, just one of them.

The code:
#include<stdio.h>
int main(void) {
int num,x,y=0;
printf("enter range:");
scanf("%i",&num);
for(x=1;x<=;x++) {
if(num%x==0) {
y++;
}
if(y==2) {
printf("it is prime number.\n");
} else {
printf("it is not prime number.\n");
}
return 0;
}
It looks like you forgot a closing bracket for your for loop. You need one between the else of the second if and your return. This is the cause of the second actual error, fatal error C1075: end of file found before the left brace '{'.
Also, for (x = 1; x <= ; x++) is not a valid for loop. The second part x <= ; is missing a value to compare against. For example, x <= 10;. That's where the syntax error error C2059: syntax error : ';' is coming from. The other complaints about semicolons are due to this error.
Edit:
Also, your assignment int num,x,y=0; is difficult to understand. I recommend you clean it up, either by putting on multiple lines or by chain assigning.
Given the information you have given us, you probably need to add or remove one or more ; then add a } somewhere after line 3. But you also may not need to do these things.
The first thing that comes to mind is the line:
for(x=1;x<=;x++) {
you have a x<= just sitting there alone, you have to put a value there.
I'm guessing that you meant:
for(x=1; x<=num; x++) {
But other than that, no other syntax errors are jumping out at me.

when I include atomic.h, GCC says No such file, why?

I want to use atomic API, and I include . I don't know how to use it! Thank you!
I have it in /usr/src/linux-headers-2.6.28-11/arch/x86/include/asm/atomic.h.
I also add -I/usr/src/linux-headers-2.6.28-11/arch/x86/include/ and -I/usr/src/linux-headers-2.6.28-11/include.
Some other errors is produced because of -DCONFIG_X86_32 and -D__KERNEL__ macro undefined.
Then I define the two macros,
some errors occurred:
/usr/src/linux-headers-2.6.28-11/include/linux/cpumask.h:600:37: error: "and" may not appear in macro parameter list
/usr/src/linux-headers-2.6.28-11/arch/x86/include/asm/processor.h:159:1: warning: "cache_line_size" redefined
/usr/src/linux-headers-2.6.28-11/include/linux/cache.h:64:1: warning: this is the location of the previous definition

/usr/src/linux-headers-2.6.28-11/include/linux/stddef.h:18: error: expected declaration before ‘}’ token
My system is ubuntu 9.04 running on Virtualbox3.0.
If you know where the file is on your HD, then you say gcc mySource.c -I/path/to/atomic
note that this assumes you include "atomic" directly. and not "some/path/atmomic.h"
