Power Function in C

 The pow function in C is a part of the math.h library and is used to calculate the power of a given base raised to a specified exponent.

 It takes two arguments: base and exponent

Syntax Power function in C:

double pow(double base, double exponent);

 base: The base number.

 exponent: The exponent to raise the base to.

Return Value:

The pow function returns the value of base raised to the power of exponent (base^exponent).

Example:

 // Program for power function in C
#include<stdio.h> 
#include<math.h>

int main() {
    double base, exponent, result;

    printf("Enter the base number: ");
    scanf("%lf", &base);

    printf("Enter the exponent: ");
    scanf("%lf", &exponent);

    result = pow(base, exponent);

    printf("%.2lf raised to the power of %.2lf is %.2lf\n", base, exponent, result);

    return 0;
}
	

Output:

Enter the base number: 4
Enter the exponent: 7
4.00 raised to the power of 7.00 is 16384.00

Usage of power function in C

 The base and exponent can be any real numbers.

 The exponent can also be a negative number, which would calculate the reciprocal of the base raised to the absolute value of the exponent.

Key Points:

 Ensure to include the math.h header file before using the pow function.

 Handle errors or invalid inputs, like raising a negative number to a non-integer exponent, which would result in a complex number (in real mathematics, not supported by C's pow function).
