C Program compilation problem [closed]

Question

I wrote a program using nano and tried to compile it using gcc command on Lx-terminal. It's showing stray error. Can anyone tell me what is the problem? For simple "hello world" program also is showing errors.

Code:

#include<stdio.h>
main()
{
printf(hello world;
}

Output:

Answer 1

The problem is with your printf line.

printf(hello world;

you are missing the closing parenthesis ")", You are also missing quotes around the text "Hello World"

change that line to:

printf("hello world");

Your final code should look like this

#include<stdio.h>
main()
{
  printf("hello world");
}

You can then compile it with this command:

gcc -o helloworld helloworld.c

You should now have an executable called helloworld that can be run by typing:

./helloworld
