pow function in C programming Language
In this tutorial, we will discuss pow function in C programming Language
Description
Pow() in C is used to find the power of the given number
The pow() function in C programming language (C library function) returns x raised to the power of y
pow(): In the C Programming Language, The pow() Arithmetic function calculate x raised to the power of y
Declaration
The declaration for the pow() in the C Programming language is
double pow(double x,double y );
Parameter or Argument
parameter of pow() function is:
x,y are the arguments of this function
Return
The pow() function returns x raised to the power of y
Required header
In this Language, The required header for the pow function is
#include <math.h>
Example
The following example shows the usage of pow()
pow function in C
program 1
#include <stdio.h>
#include <math.h>
int main()
{
printf("The Power value of pow(2,3) is %f\n",pow(2,3));
printf("The Power value of pow(3,4) is %f\n",pow(3,4));
getch();
return 0;
}
When the above program is compiled, it will produce the following result
The power value of pow(2,3) is 8.000000
The power value of pow(3,4) is 81.000000
Example 2
#include <stdio.h>
#include <math.h>
int main()
{
//define temporary variable
double val1,val2;
double result;
printf("Enter the number one :");
//get first input from user
scanf("%lf",&val1);
printf("Enter the number two :");
//get second input from user
scanf("%lf",&val2);
//calculate power
result=pow(val1,val2);
//Display power value
printf("power value is: %lf\n",result);
getch();
return 0;
}
When above program is compiled, it will produce the following result
Enter te number one :5 Enter te number two :6 Power value is :15625.000000
