extern int eg_i = 0;
int main(){
++eg_i; // 1
return 0;
}
This code surprisingly throws no compile error.
Because if an extern variable is declared with initialization, it is taken as the definition of the variable as well.
I didn't know…
Example:
//
test.h
#define MAX 3

Why not use Vector, or Vector, or an Array, or another data type?

I'm using RTKLIB (it is not important), and inside a directory there are multiple .c files:
rtcm.c
rtmc2.c

Inside the same directory, I created a main.c file, where the program is executed.
Inside main.c I call different…
In the following C code:
printf( "Coffee!" );
and
scanf("%d", &coffee);
printf("\nI’m baking %d coffee!", coffee);
Are "Coffee!" and coffee considered arguments?
I am messing around with python, and am trying to make a simple data cleaning program. I'm trying to pass the title values from the read_excel module, to the output module. But, it keeps saying name title is not defined. Here is my code:

I know that the title is not clear but sorry for my english I did not find how to formulate my question. So I hope below I could explain it further.
In fact I was reading a code where the user, when he was defining a class (let's called X), he…
What is the exact definition of source code and code?
printf("hi\n");
Is this a source code or a code?
int main(void)
{
printf("hi\n");
}
This is definitely a source code, right?
I have two pointer variables as data members. How do I make copies of these two data members? How do I make a deep copy constructor for this? I tried many times, but it's not working.

I am trying to make a definition that takes an input (name as string) and checks if the name is in a set list.
If it is, the program will continue.
If it isn't, it will give the user 2 more chances to enter their name…

Here is a Scheme code to produce the permutations of a list of elements:

I want my procedure to print something, then return that something. I tried this

Shouldn't it be as straightforward to say that this procedure displays x at first then returns it as it's expressed at the…
