C++ Arithmetical Programming Language Function | C++ Arithmetical Programming Language Function Example

C++  Arithmetical Function

C function where are used to perform mathematical   operations program are called arithmetical function.  This library are inbuilt in arithmetical function in c languge.

“math.h” and “stdlib.h” header files support all the arithmetical function in c language.

List of arithmetical function given below:

1.pow()

2.sin()

3.sqrt()

4.log()

 

 

Fig: C++  Arithmetical   Function 

1.pow()

This is used to find power of given number.

Program

#include<iostream.h>

#include<conio.h>

#include<math.h>

void main()

{

int     i,n,j;

cout<<“Input two number”;

cin>>i>>j;

n=pow(I,j);

cout<<n;

getch();

}

Output:

Input two value

5

3

125

 2.sin()

This function is used to calculate  sine value.

Program

#include<iostream.h>

#include<conio.h>

#include<math.h>

void main()

{

int     i,n;

cout<<“Input  number”;

cin>>i;

n=pow(I);

cout<<n;

getch();

}

Output:

Input  value

90

0

3.sqrt()

This f unction is used to find the square root of the argument  passed to  this function.

Program

#include<iostream.h>

#include<conio.h>

#include<math.h>

void main()

{

int     i,n;

cout<<“Input  number”;

cin>>i;

n=sqrt(I);

cout<<n;

getch();

}

Output:

Input  value

25

5

4.log()

This function is used to calculate  the natural logarithm.

Program

#include<iostream.h>

#include<conio.h>

#include<math.h>

void main()

{

double  n,x;

x=72.325;

n=log(x);

cout<<n;

cout<<x;

getch();

}

Ouput:

72.325
