Math H Or CMATH

Hii sir, I am Student of BCA I wants to Know the difference between math.h and CMAT And Also Differentiate iostream and iostream.h in C++?

[sumit]

As you Asking for the difference between MATH.h and CMATH the Differnce is As Follow

Math.H is A Header File In C Used for the Mathematical Functions into the Program
But It is Also Used By C++

cmath is a C++ library header File The stuff from math.h in the correct namespace plus a lot more Addition With Some More Numerical Functions


Difference About the iostream and iostream.h

iostream is a C++ library header. It declares the eight global streams (std::cin, std::cout, etc)

iostream.h is not, and never was part of standard C++ (or C, of course). It was part of the IO library from around 1990, but by the time the first C++ standard was published in 1998, it was history.


Here I am giving you Some Header Files of the C++ Languages :

<cstdlib>
General purpose utilities: program control, dynamic memory allocation, random numbers, sort and search

<csignal>
Functions and macro constants for signal management

<csetjmp>
Macro (and function) that saves (and jumps) to an execution context

<cstdarg>
Handling of variable length argument lists

<typeinfo>
Runtime type information utilities

<typeindex> (since C++11)
std::type_index

<type_traits> (since C++11)
Compile-time type information

<bitset>
std::bitset class template

<functional>
Function objects, designed for use with the standard

algorithms

<utility>
Various utility components

<ctime>
C-style time/date utilites

<chrono> (since C++11)
C++ time utilites

<cstddef>
typedefs for types such as size_t, NULL and others

<initializer_list> (since C++11)
std::initializer_list class template

<tuple> (since C++11)
std::tuple class template

<any> (since C++17)
std::any class template

<optional> (since C++17)
std:ptional class template

<variant> (since C++17)
