Power Function in CThis article will discuss the power function and its various examples in the C language. The power function is used to find the power of any given number. The power function is a predefined library function of the math.h header file, and we need to import the math.h header file in our program while using the pow() function. In other words, a pow() function is used to calculate the power of the base number (x) by raising the power of (y) as (x^{y}). For example, we take base as 2 and power as 5, the power of a number using the pow(2, 5) function to return a value as the 32. Similarly, we pass 3 as the base and 4 as the exponent number to raise the power of the base number using the pow(3, 4), which returns results as 81. SyntaxThe pow() function has two integer arguments for raising the power of base value (x) by the exponent (y). Parameters:
Program to find the power of an integer number using the pow() functionLet's consider an example to get the power of an integer number using the pow() function in the C programming language. Program2.c Output Enter the base value from the user: 7 Enter the power value for raising the power of base: 5 7 to the power of 5 is = 16807 Program to calculate the power of double data value using the pow() functionLet's consider an example to demonstrate the pow() function using the double data values in the C programming language. Program2.c Output Enter the base value from the user: 2.9 Enter the power value for raising the power of base: 8.3 2.9 to the power of 8.3 is = 6884.99 Program to get the power of a number using a userdefined functionLet's consider an example to create a userdefined function to get the power of a number in the C programming language. Program1.c Output Enter the base value: 25 Enter the power value: 6 25 to the power 6 is = 244140625 Program to get the power of a number using the recursion function and pow() functionLet's consider an example to find the power of a number using the recursion function and pow() function in the C programming language. Program.c Output Enter the base value from the user 5 Enter the power value from the user 6 5 to the power of 6 is = 15625 ConclusionA power function is used to find the power of any numeric data (int, float, double) using the pow() function. A power function has two arguments: the base number and the exponent number. The base number represents the power to be calculated, and the exponent defines the power of the base value.
