How to run c program in termux in android

What is C

 C is a general-purpose, imperative computer programming language, supporting structured programming, lexical variable scope and recursion, while a static type system prevents many unintended operations.

How to install C ?

Open termux and type following command

• >  pkg install clang

You can use any text editor according to your comfort in this tutorial I am using nvim 

To install nvim in termux type this command 

• > pkg install nvim

To write your program first you have to create a file , you can create a file using this command 

• > touch filename.c

Here filename may be anything according to your wish example hello.c 

After that open your file in editor using this command 

• > nvim filename.c

We write a simple c program in "C" language 

#include <stdio.h>
int main()
{
   printf("Hello, World!");
   return 0;
}

Now press ESC then :wq to save your file in nvim , same is applicable for vi and vim also and if you are using nano text editor then press ctrl + s to save your file 

To compile your program type this command

 gcc filename.c -o filename

For example Above we have created a file named as hello.c 

To compile this c program we will write command > gcc hello.c -o hello

 

After that execute your program using this command 

./filename

In this tutorial Our filename is "hello" so we will use command ./hello to execute it 

You have created your first program in c aud run it in android well 

Thankyou guys  :)
