1.Difference between C & C++

 

s.no.	C	C++
1)	C follows the structure or procedural oriented language.	C++ object oriented language.
2)	Data is less secured in C.	In C++, Data is more secured.
3)	C follows the top-down approach.	C++ follows the bottom-up approach.
4)	C does not support function overloading.	C++ supports function overloading.
5)	In C, scanf() and printf() are mainly used for input/output.	C++ mainly uses stream cin and cout to perform input and output operations.
6)	Operator overloading is not possible in C.	Operator overloading is possible in C++.
7)	C programs are divided into procedures	C++ programs are divided into functions and classes.
8)	C does not support the inheritance.	C++ supports inheritance.
9)	#include<stdio.h> Std -standard i -input o-output input - scanf output- printf	#include<iostream.h> i-input o-output stream input - cin output - cout
10)	#include<conio.h> Console input output Getch clrscr	#include<conio.h> Console input output Getch clrscr
11)	main() { Program; }	Void main() { Program; }
12)	Sample program #include<stdio.h> #include<conio.h> main() { clrscr(); printf("hi hello\n"); printf("welcome to traineetech"); getch(); }	Sample program #include<iostream.h> #include<conio.h> void main() { clrscr(); cout<<"hi hello\n"; cout<<"welcome to traineetech"<<endl; getch(); }
13)	No OOPs concept	OOPS -object oriented programming structure Inheritance - generation Abstraction - data hiding Encapsulation - Data binding Polymorphism - Multi task Object - collections of data Class - collections of object
