Explanation
The program calculates and prints the power of two numbers entered by the user. Specifically, it computes \( x \) raised to the power \( y \).
Header
The code begins with including the standard input-output header files using #include <stdio.h> and #include <math.h> for mathematical functions.
Variable Declaration
The main() function is defined, and two variables of type long double are declared:
long double d: Stores the base number.long double m: Stores the exponent.
Program Description
The program prints a description message for the user to understand its functionality and gives an example of the operation.
User Input
The user is prompted to enter a base number and its exponent. The input is read using scanf("%Lf %Lf", &d, &m);.
Power Calculation and Output
The program calculates the power using the pow function from the math library and prints the result:
printf("\n Power for the entered number %.1Lf to the power %.1Lf is: %.1Lf", d, m, pow(d, m));: Prints the base number, the exponent, and the result of raising the base to the power of the exponent.
Program End
The program ends with printf("\n"); to print a new line and return 0; to indicate successful execution.

Output
Program to print the power of the two numbers entered by the user. (Example: 2 3) = 2 to the power 3 = 8
Enter a number and its power for which you want to print x raised to the power y (Example: 3 6) -
and press enter: 3 7
Power for the entered number 3 to the power 7 is: 2187.0
