Lets Begin.

Create your main class and add the include stdio.h

#include <stdio.h>

int main() {

}

Now we shall crate our variable. Lets call it Name and allow it to accept 1024 bytes

To do this we use the char* variable

char name[1024];

The [1024] after name is optional and is called the buffer. It defines how many bytes of information the applicatoin can hold. This can cause problems with buffer overflow exploits

Now we need to have some user interaction. Lets make the application ask for the users name

printf("Please enter your name!\n");

Ok to allow the user to enter their name we use the scanf function

The scanf function should look like this

scanf("%s", name);

Notice our variable is mentioned there. this just tell the scanf function where to store the user input

Now we should make the application do a greeting. To make it greet simply print a message using the variable.

To print the variable we need to use %s and define what it is at the end. to do this add the following line.

printf("Hello %s congradulations on your C Application\n", name);

Right thats your basic C application using Variables. This can be run in Linux, Windows, and Mac

The final code should be similar to bellow

#include <stdio.h>

int main() {
     char name[1024];
     printf("Please enter your name below!\n");
     scanf("%s", name);
     printf("Hello %s Congrats on the C app\n", name);

     return 0;
}
