I am using Vsc to write my program in C, the program should return an error but nothing is shown, only the final code is provided (code = 3221225477), how can I get the error displayed?
The final output is: [Done] exited with code=3221225477 in 0.569 seconds
#include <stdio.h>
#include <stdlib.h>
int main(){
char x = 'a';
printf("%s", x); //Error cause i'm using %s for a char
}
P.s. I have already installed .Run and the C / C ++ extension
The Microsoft C/C++ extension if configured properly (problemMatcher in tasks.json) should also trigger similar errors based on the compiler you select.
After investigation, you might get some help from the clangd extension.
Install the extension in VS Code from https://marketplace.visualstudio.com/items?itemName=llvm-vs-code-extensions.vscode-clangd
Open your project folder in VS Code and open the source file (like main.c).
Then this extension should run clangd in the background and show a warning "Format specifies type 'char *' but the argument has type 'char' (fix available)".

I'm trying to learn how to program in C.
I'm simultaneously learning C, C++, & Java. I have also coded in html and javascript successfully making rich websites.
I'm following video lessons on skillshare. Through VirtualBox I've set up a ubuntu installation, created lesson001.c, and attempted to compile it by entering "gcc lesson001.c"
The program:
#include <studio.h>
int main(){
printf("hello, world!\n");
return 0;
}
The error:
lesson001.c:1:10 fatal error: studio.h: no such file or directory.
The instructor is walking through the coding lesson on a pre-configured linux system, so he does have the same errors. It is frustrating that a comprehensive paid lesson set does not include critical setup parameters.
additional info: "gcc -v" returns about 20 lines of information on gcc 9.3.0, so I believe it is installed correctly.
Thank you
Change the #include <studio.h> declaration to #include <stdio.h>. A header file named studio.h does not exist in the standard library.
stdio stands for "standard input/output," and has nothing to do with "studio"! 😀
It should be stdio instead of studio.
stdio stands for Standard Input Output
Correctly formatted code :
#include <stdio.h>
int main(){
printf("hello, world!\n");
return 0;
}
I am trying to do a project in C but I have problems with the string #include<stdio.h>, I tried several tutorials but none of them worked, my code:
#include <stdio.h>
int main () {
int age;
printf ("Enter age:");
scanf ("% d", age);
printf ("age is% d", age);
return 0;
}
The problems are 2:
#Include errors were encountered. Update includePath.
Unable to open source file error code "stdio.h".
For this project I have created a folder, in which there is a folder called .dist and my Main.c file
(I have attached an image to be clearer)
Could anyone tell me how I can solve this problem?
The error showed in the first picture is due to the incorrect setting of the IntelliSenseMode of the editor. I bet that you have installed gcc compiler on your computer and you should also set "gcc" on the IntelliSenseMode of the editor which, by default, has a wrong value that freakout when it reads "#include <stdio.h>".
Thank you very much for all the advice, I added the files c_cpp_proprietes.json, launch.json, task.json and I added the Microsoft C / C ++ extension, I also fixed the code, but the problem remains before, also because I don't know what code I have to put in the files that I added maybe?
First, go to your C/C++ extension configuration and change your compiler path to gcc.exe
Then change Intellisense mode to windows-gcc-x64
Attached a screenshot for better understanding.
[VS Code
So there are 2 problems here:
1st: In the 7th and 8th line of code you have written "% d" which should be "%d" to define the integer data type.
2nd: Again in the 7th line of code you forgot to put "&" before the variable "age" which provides the address of the variable to put the entered value.
For better understanding attaching image.
I am trying to run a simple program below on my mac using CodeBlocks IDE:
1. #include <stdio.h>
2. int main()
3. {
4. // printf() displays the string inside quotation
5. printf("Hello, World!");
6. return 0;
7. }
but I get the following error:
error: expected identifier or '('
As the machine is trying to compile, I think gcc compiler is working fine.
Remove the line numbers, that's the problem.
try in different IDE and find out where the problem is whether in Codeblocks IDE configuration or with the compiler itself.
I have visual studio installed in my system. So its corresponding compiler and environment variables are set. When i try to compile c file using cl command, it works fine. Now i zipped mingW from another system and extracted it to my system. Say i have it in D:/mingW. Now i have created a batch file for compiling the c file. The contents of the batch file are,
set gccPath=D:/mingW/bin
%gccPath%/gcc.exe -c -std=c99 -o myC.o ../myC.c -I..\.
When i run this batch file, it is producing few errors.
One such error is
stdio.h:209:71: error: macro "snprintf" requires 5 arguments, but only 4 given
The above error might be due to the fact that compiler takes the stdio.h of visual studio instead of mingW's default header file.
Another error is,
error: previous declaration of 'xxxxFun' was here
What should i change in the batch script to compile the c file completely using mingW.
Compilation process is successful when we use Visual Studio, but throws error if we use gcc for the same set of files
EDIT:
I fixed the latter error.
Also the first error doesn't occur when stdio.h is included at first. But if we include stdio.h at the middle of the include section, the error comes.
#include <string.h>
#include <assert.h>
#include <minmax.h>
#include "myFunctions.h"
#include "MyModule.h"
#include <stdio.h>
When we have stdio.h at last as shown, the error is coming. If we move the line #include <stdio.h> to any other lines above #include <MyModule.h> , the specified error is not coming. Any reason behind this strange behavior?
Check whether you are defining snprintf using macros in any of your header files. This error may be caused due to incorrect/unnecessary macro.
When I build and run C using Sublime Text 3, a warning message show up.
clang: warning: treating 'c' input as 'c++' when in C++ mode, this behavior is deprecated
Actually, it is my first time to use Sublime Text 3 for C programming, so I wonder how to take care of this warning message.
My source code and the output are as below.
soruce:
#include <stdio.h>
int main(void) {
int a = 3;
printf("%d\n", a);
}
output:
clang: warning: treating 'c' input as 'c++' when in C++ mode, this behavior is deprecated

Please let me know the solution.
Does this mean you have saved your file as file.cpp instead of file.c? (Sorry, I can not comment, I have few points.)
