Study Notes
Introduction to C++
- C++ program consists of several parts, including comments, preprocessor directives, and functions.
The Parts of a C++ Program
- A C++ program can have comments, which start with
//and are ignored by the compiler. - The
#includedirective is a preprocessor directive that tells the compiler to include a file. - The
using namespace std;statement specifies which namespace to use. - The
int main()function is the entry point of the program, where execution begins. - The
{}block is used to group statements together in a function.
C++ Program Structure
- A C++ program typically includes a
mainfunction, which is the starting point of the program. - The
mainfunction contains a block of code, which is enclosed in{}.
