## Main Question or Discussion Point

hello everyone,

one short question. it is said function sqrt() takes argument inside the parenthesis. sometimes word parameter is also used. are they interchangeable? i am speaking in terms of c++.

is int main() has any similarity to math functions such as f(x)=2x+7. but the problem is int main() does take any value inside the "()". i am a beginner. so short explanation is enough. many many thanks for this help and leading me on the right path.

cheers
