C Program - Power of a Number for Elements inside C Array

This C program calculates the power of each element in an array to a fixed exponent and displays the results. 

#include <stdio.h>
#include <math.h>

int main()
{

    int numbers[] = {2, 3, 4, 5, 6};
    int exponent = 3;

    int number_of_elements = sizeof(numbers)/sizeof(numbers[0]);

    printf("Number of elements: %d \n", number_of_elements);

    for (int x = 0; x < number_of_elements; x++)
    {
        printf("Number: %d, Exponent: %d, Result: %d \n", numbers[x], exponent, (int)pow(numbers[x], exponent));
    }

    return 0;

}

Result: 

Number of elements: 5
Number: 2, Exponent: 3, Result: 8
Number: 3, Exponent: 3, Result: 27
Number: 4, Exponent: 3, Result: 64
Number: 5, Exponent: 3, Result: 125
Number: 6, Exponent: 3, Result: 216

Here's a line-by-line explanation of the code: 

#include <stdio.h>
#include <math.h>

These are header files which provide the necessary libraries to perform input/output operations and mathematical calculations using the pow() function. 

int main()
{
    int numbers[] = {2, 3, 4, 5, 6};
    int exponent = 3;

    int number_of_elements = sizeof(numbers)/sizeof(numbers[0]);

This declares an integer array numbers and initializes it with some values. It also declares an integer variable exponent and initializes it to 3. The number_of_elements variable is initialized to the size of the numbers array divided by the size of one element in the array. 

    printf("Number of elements: %d \n", number_of_elements);

    for (int x = 0; x < number_of_elements; x++)
    {
        printf("Number: %d, Exponent: %d, Result: %d \n", numbers[x], exponent, (int)pow(numbers[x], exponent));
    }

    return 0;
}

This displays the number of elements in the numbers array using printf(). Then, it loops through each element in the numbers array using a for loop, calculates the power of the element raised to the exponent using the pow() function from the math.h library, and displays the result using printf(). Finally, the program ends with a return value of 0.
