Programming Languages

  • How to compile and run files of different languages in the terminal

Run C++ files

compile .cpp & .h files together​

syntax: -Wall: check for errors​

  • -o: is an output file
  • output file name: zzz
  • .cpp and .h files
  • old method of building

    g++ -Wall -o zzz xxx.cpp abc.h

  • new method of building

    g++ -Wall -o zzz xxx.cpp

  • run built file

    ./zzz

Run C files

same as above but add -x c when compiling​

g++ -x c -Wall -o zzz xxx.c abc.h

OR​

clang -o zzz xxx.c abc.h

OR​

make xxx

If .h header file is in another directory need to use -I​

g++ -I /fullpath/myproject xxx.cpp /fullpath/myproject/header/yyy.h

use ./ to run file​

./zzz

if no output file name is defined earlier​

  • ouput file will automatically create an a.out file
  • to run

    ./a.out

Run C# files

  • Need to have Mono platform to compile and run code
    • if using MacOS

      brew install mono

compile file​

mcs xxx.cs

  • xxx.exe will be created

run file​

mono xxx.exe

Run Java files

  • xxx.java file name must be the same as public class name
  • note: it is case sensitive

compile xxx.java file with javac in terminal​

javac xxx.java

java class will be created, run class file with java​

java xxx

java 11 onwards, class will not be created, javac not required​

  • compile and run java file

    java xxx.java

compile and run at the same time​

javac xxx.java && java xxx

using package​

  • e.g.: Main.java
package com.example.java;

public class Main {
  public static void main(String[] args) {
    System.out.println("Hello from Java!");
  }
}

at root directory of project​

compile file​

javac ./com/example/java/Main.java

run file​

java com.example.java.Main

using modularity​

  • compile

    javac -d ./mods/ --module-source-path src $(find src -name "*.java")

  • run without optional dependencies

    java --module-path mods/ -m com.domain.module/com.domain.module.Main

  • run with optional dependencies

    java --module-path mods/ --add-modules com.domain.optionalmodule -m com.domain.module/com.domain.module.Main

Run Typescript files

run typescript files without compiling with ts-node in terminal (no javascript created)​

ts-node xxx.ts

compile xxx.ts file with tsc in terminal​

tsc ./xxx.ts

javascript file will be created, run file with node​

node xxx.js

Run Javascript files

run with nodeJS​

node filename.js

open nodejs shell​

node

Run Python files

run with python 2​

python2 filename.py

open python 2 shell​

python2

run with python 3​

python3 filename.py

open python 3 shell​

python3

Run Ruby files

ruby filename.rb

open ruby shell​

irb

Run assembly files

  • nasm compiler must be installed
    • if using MacOS

      brew install nasm

compile & run x86 32 bit files​

compile​

nasm -f macho xxx32.asm && ld -macosx_version_min 10.7.0 -o xxx32 xxx32.o

run​

./xxx32

compile & run x86_64 64 bit files​

compile​

nasm -f macho64 xxx64.asm && ld -macosx_version_min 10.7.0 -lSystem -o xxx64 xxx64.o

run​

./xxx64

Run Groovy

Open GroovyShell to use the dynamic interpreter on the terminal​

  • in the command line type groovysh

Open GroovyConsole to open an external UI interface editor​

  • in the command line type groovyConsole

Execute groovy code on the command line​

  • groovy -e "println 'Hello, World!'"

Run groovy file​

  • groovy hello.groovy or groovy hello

Compile Latex file

xelatex filename.tex
