Question

     Write comments of the C program codefor the given example to explain your understanding of each line of the code

/*******************************************************************

Your Full Name: ------------------------------

Add comments after each program statement or before segments of code to explain the code.

Your comments should explain the purpose / rationale for the given code.

If the programming concept has not been covered yet, run the program and figure out the purpose of the code.

**********************************************************************/

#define _CRT_SECURE_NO_WARNINGS       

#include <stdio.h>                   

#include <conio.h>  

#include <math.h> // define various mathematical functions

int main()

{

       float num = 0; //requires a casting from integer to float

       float result = 0; //requires a casting from integer to float

       float answer = 0; //requires a casting from integer to float

     //Information about the number

       printf(" Enter a number ", &num); //Let the user enter a number

       scanf (“%f”, &num); //Check the number that the user entered

       result = num;

       result = result * num;

       result = result * num;

       result = result * num;

       result = result * num;

       printf (“ Result of calculation = %.2f “, result);

       answer = pow (num, 5);

       if (result == answer)

          printf (“ Calculation is correct!”);

       else

          printf (“ Calculation is not correct.”);

       _getch();

       return 0;

}

Explanation / Answer

#define _CRT_SECURE_NO_WARNINGS #include #include #include // define various mathematical functions int main() { float num = 0; //requires a casting from integer to float float result = 0; //requires a casting from integer to float float answer = 0; //requires a casting from integer to float //Information about the number printf(" Enter a number ", &num); //Let the user enter a number scanf (“%f”, &num); //Check the number that the user entered result = num; // set result to num result = result * num; // change result to num*num result = result * num; // change result to num*num*num result = result * num; // change result to num*num*num*num result = result * num; // change result to num*num*num*num*num // finally here result is num to the power of 5 printf (“ Result of calculation = %.2f “, result); // print the result answer = pow (num, 5); // calculate num to the power of 5 using pow from math library if (result == answer) // check if result from math library and our calculated answer matches or not. printf (“ Calculation is correct!”); // if matches, print it's correct else printf (“ Calculation is not correct.”); //if doesn't match, print it's not correct _getch(); return 0; }
