Study Notes
C++ Program Structure
- A C++ program typically starts with a comment, which is denoted by
//. - The
#includedirective is a preprocessor directive that tells the compiler to include a file.
Namespace and Main Function
- The
using namespace std;line specifies which namespace to use in the program. - The
int main()line marks the beginning of the function namedmain, which is the entry point of the program. - The
{symbol denotes the beginning of a block of code for themainfunction.
Output Statement
- The
coutstatement is used to output text to the console.
