GCC, the GNU Compiler Collection - GNU Project
The GNU Compiler Collection includes front ends for C, C++, Objective-C, Objective-C++, Fortran, Ada, Go, D, Modula-2, COBOL, Rust, and Algol 68 as well as libraries for these languages (libstdc++,...). GCC was originally written as the compiler for the GNU operating system.
Installing GCC
The latest version of this document is always available at https://gcc.gnu.org/install/. It refers to the current development sources, instructions for specific released versions are included with the sources.
GCC mirror sites
Include the URL of the gcc.gnu.org mirror area, the country/city where the mirror is located, and a contact e-mail address (and name if appropriate).
GCC Releases
GCC releases may be downloaded from our mirror sites. Important: these are source releases, so will be of little use if you do not already have a C++ compiler installed. As one option, there are pre-compiled binaries.
Downloading GCC
The source distribution includes the Ada, C, C++, Objective-C, COBOL (GCC 15 and later), D (GCC 9 and later), Fortran, Go, Modula-2 (GCC 13 and later) and Algol 68 (GCC 16 and later, experimental) compilers, as well as runtime libraries for C++, Objective-C, COBOL, Fortran and Algol 68.
optimizing compiler produced by the GNU Project, key component of the GNU tool-chain and standard compiler for most projects related to GNU and the Linux kernel.

Why is GCC the only compiler that cares deeply about C?
Microsoft doesn't care about C. The win32 API is an ANSI C API and Windows programs haven't been written in C regularly since the Windows 3.x era. They lagged behind for a while, not implementing C99, but have since turned around and MSVC is C17 with more or less all the features. They even have a standards-compliant preprocessor now, available with a project setting or switch. It's weird that you have to specifically ask for the compliant preprocessor, but making that the default would break a lot of old projects. But anyway, you can do modern C in MSVC now, they're up to speed. Clang is more or less on par with GCC, and they both represent the state of the art of C. More on reddit.com

1 day ago - This gross underestimate was due to the fact that I thought parsing and making sense of C is simple. You probably think the same. What I did not expect was how many dark corners this language has, especially if you want to parse real-world programs such as those written for GCC or if you are more ambitious and you want to parse the Linux or Windows NT sources (both of these were written without any respect for the standard and with the expectation that compilers will be changed to accommodate the program).

Try to compile your code normally as
gcc test.c
If you get default output file a.exe,then go for
gcc test.c -o test.exe

I would suggest you go through this compilation instruction :-
gcc -o test.exe test.c
I believe this code runs perfectly on your windows system.Please inform if it doesn't!

May 20, 2022 - C is a well-known programming language, popular with experienced and new programmers alike. Source code written in C uses standard English terms, so it's considered human-readable. However, computers only understand binary code. To convert code into machine language, you use a tool called a compiler. A very common compiler is GCC (GNU C Compiler).

This is actually a well-known concept called bootstrapping. Basically, there exists, somewhere, a minimal C codebase to build a version of GCC that's capable of building the current GCC codebase. Self-hosting languages have been doing things like that for decades.

Creating a compiler that is written in the same language that it compiles is called bootstrapping. The wikipedia article describes a number of ways that a compiler can be bootstrapped.
Given your restriction that you only have a post-4.8 G++ source code and no pre-built binaries for your target platform (no existing C++ compiler), then bootstrapping the G++ compiler can be done by means of cross-compilation.
When bootstrapping a compiler using cross-compilation, you build several versions of your compiler
- On your PC, you install a C++ compiler (can be any C++ compiler, doesn't have to be G++)
- Using that compiler, you create a G++ cross-compiler that can execute on the PC and generates code for the target platform
- Using the G++ cross-compiler you just built, you create a native G++ compiler that can run on the target platform and create code for it.
- You are done. You have created a C++ compiler for the new platform.
If you also don't have a PC (or similar) to perform the initial steps on, then you are indeed stuck, but the chance of being in that situation and trying to bootstrap a compiler are negligible.

When you compile C++ programs, you should invoke GCC as g++ instead. The gcc program accepts options and file names as operands. Many options have multi-letter names; therefore multiple single-letter options may not be grouped: -dv is very different from -d -v.

r/C_Programming on Reddit: Why is GCC the only compiler that cares deeply about C?
December 22, 2024 -
From what I've seen both Clang and MSVC lack several C features from many different versions, while GCC has almost all of them. This isn't the case with C++ where the three compilers have a very similar amount of features inside their pockets.
This makes me feel like I'm forced to use GCC if I wanna everything in C. Btw, I'm on Windows 10.

MSVC implements ISO C17, Clang is practically a drop-in replacement for GCC and there are many smaller C compilers as well. If you are looking for GNU extensions not part of the C language, you will obviously find them in GNU GCC.
