The first c++ program
Important points about a C++ program
- Every C++ program starts with including header files containing library of functions to be used in the program.
- Every C++ program starts with a main( ) function.
- Every statement in C++ program must end with a semicolon ;(unless it is a comment)
- A main function defines a single or multiple set of statements to execute within opening and closing braces {}.
To write the first c++ program, open the Turbo C and write the following code:
#include< iostream.h >
void main()
{
cout<<"welcome to Tutorial Zone";
}
#include < iostream.h > includes the standard input output library functions. The cout is defined in iostream.h
Output:
int main() The main() function is the entry point of every program in c++ language.
cout The cout is used to print data on the console.
