Compiling C++ code

C++ Compilation on Linux Mint

C++ Compilation Process:

• We write C++ code in files with .cpp or .c++ extensions.

• We give these files to C++ compiler(which is g++) to compile.

• The compiler compiles our source files into an executable file(a binary file).

• We run or execute that binary file when we want to use our program and get the output.

• So, its a two-step process:

  1. Compile

  2. Run or Execute

Note: Binary files on linux generally have no extensions.

Steps:

To compile:

g++ -std=c++17 -Wall -Wextra hello.cpp -o hello

Here:

• g++ is the compiler name.

• -std=c++17 → This says to the compiler that our code is using c++17 standard (latest version).

• -Wall and -Wextra → give warning messages for errors in our code.

• hello.cpp is our c++ source file name.

• -o specifies the output(binary) file name, which is hello.

To run or execute:

./hello

Runs the hello binary which is present in current directory.

Done!
