Math.h is a header file that contains all the math related functions like finding square root, absolute values etc. While string.h is a header file which contains all functions to perform string related operation

General form of c program is... Global declarationsint main(parameter list){statement sequence}return-type f1(parameter list){statement sequence}return-type f2(parameter list){statement sequence}...return-type fN(parameter list){statement sequence} This form is mainly concerned with Functions and Declarations. Significance of math.h file math.h header files drives hundreds of maths functions along with one macro. This header file returns result as double and takes double as an argument. Significance of string.h file string.h header file drives string related functions . This header file defines any one variable type, one macro, and number of functions. Basically header file contains Declarations, Definitions, and Macro of related number of functions which is defined in that particular header file. Thanks Regards Mahesh v Kondawar read less

Hello IshwariWe know we have already defined data types like int, char, float, double.Let's take intWhen we declare int i ;It simply means an area of 2 Bytes(architecture dependent) gets allocated and the area is named as i and as our houses get some address in a street, in the same manner, this area...

Hello IshwariWe know we have already defined data types like int, char, float, double.Let's take intWhen we declare int i ;It simply means an area of 2 Bytes(architecture dependent) gets allocated and the area is named as i and as our houses get some address in a street, in the same manner, this area will also have an address.Now if we want some area which must contain say some 5 Bytes and that area has to be divided into 3 areas.we want to give the first division to an int , the 2nd division to a char, the 3rd division to another int.So this type of data type is not already defined.So we need to make a data type like this on our own. How to do that?We use structure.struct datatype{ int i; char c; int j;};Now if we declaredatatype x;Then x will have our desired memory allocation.Math.hhas function definitions of the mathematical functions that we use.example : pow()Similarly, string.h has functions that we use t manipulate strings. read less

Hi Ishwari, I am glad to see students like you who are keen to learn to programme. As we all know that c is an excellent programming language which made a platform for various other software and operating systems. To make it such a secure language header file were made, which includes several functions. The header file like math.h is responsible for doing several mathematical calculations like power calc, sqrt calc and several trigonometrical calc and string.h is accountable for doing wonders like string copy, concatenation, changing upper case letters to lower case and vice versa with strings(a combination of characters). The syntax for including math.h and string.h is:-#include<math.h>#include<string.h>Thank you. I hope this will help you. Good luck. read less
