what is special about main() and how is it different from other functions (im new to cpp)

[waxen snow]

ive seen people put a lot of emphasis on the main function in cpp, however i cant tell how its different from other functions. im also not sure if functions in cpp have to be called like python so id like some clarity on that pls

الدالة main() هي النقطة البداية لبرامج C++ وتُستدعى أولاً. يمكنها إرجاع قيمة للتحكم في نجاح أو فشل البرنامج، ويمكنها أيضًا استقبال معاملات من خط الأوامر. تختلف في صيغتها عن الدوال الأخرى وتستخدم للتحكم في تنفيذ البرنامج والتفاعل مع البيئة الخارجية.

the starting point for any cpp program is always function with following signature:

int main();

or, alternatively if you want to take in command line arguments

int main(int argc, char** argv);

[latent mauve]

is ** a pointer referring to another pointer?

[void robin]

char** is an address that points to multiple char*

char* is an address that points to multiple char

the number of char* is provided in argc

the number of char in a char* can be fetched by reading for the /0 (null terminator character)

look up “pointer arrays” on google

[real pawn]

yeah, because strings in c are represented as a pointer to char
