C
c is a procedural programming language
in c we use printf function
in c we use scanf function as standard input
c-programe the main function could not return a value
in c we use #include<stdio.h>as inclusion file
c is a topdown approach
In C memory allocation is done with malloc statement
memory is
deallocated in C using free statement
In C DATA IS NOT SECURED
FOCUS ON PROCEDURES
PROGRAMS ARE DECOMPOSED
INTO FUNCTIONS
DOES NOT PROVIDE
DEFAULT ARGUMENTS
c is low level language
In C,DATA can be MOVE openly around in the system from
function to function
C is a collection of FUNCTIONS.
C++
c++ is object oriented
in c++ we use cout<< as a
output function.
in c++ we use streame cin>> for input
in the c++ the main function should return a value
In c++ we use #include<iostreame>as inclusion file.
c++ is bottom up approach
in C++ it is done through new keyword
in C++
deallocation takes place through delete.
In C DATA IS SECURED
FOCUS ON DATA
INTO OBJECTS
PROVIDES
c++ is sn high level language
In C++,DATA is HIDDEn.It can not be accessed by external
Functions
C++ is a collection of FUNCTIONS and/or CLASS.
