First Program

C Program

#include <stdio.h>
int main()
{
    printf("Hello, World\n");
    return 0;
}

C++ Program

#include <iostream>
using namespace std;
int main()
{
	cout << "Hello, World" << endl;
	
	return 0;
}

Both programs looks pretty much similar isn’t it ? but, there are some differences to note and understand.

Similarities:

  • #include : This is a Preprocessor directive, instructs the C/C++ compiler to “include some other file/code into current file/code, usually used to include header files” (stdio.h for C and iostream for C++ in this example).
  • int main () :
  • { and }
  • return 0;

Differences:

  • stdio.h
  • iostream
  • using namespace std;
  • printf() and \n
  • cout and endl
