Solution
Here is a step-by-step guide for Arun to accomplish the task in C:
- First, Arun needs to include the necessary header files. In this case, he needs to include stdio.h for input and output functions.
#include <stdio.h>
- Next, he should declare the main function. This is where the main logic of the program will be written.
int main() {
- Inside the main function, Arun should declare an integer variable to store the user's input. Let's call this variable 'num'.
int num;
- Now, Arun should prompt the user to enter an integer. He can use the printf function for this. Then, he should use the scanf function to read the user's input and store it in the 'num' variable.
printf("Enter an integer: ");
scanf("%d", &num);
- After getting the user's input, Arun should declare a constant pointer to a constant integer. He should initialize this pointer with the address of 'num'.
const int *const ptr = #
- Now, Arun can print the original value of 'num' and the value accessed through the pointer. He can use the printf function for this.
printf("Original value of number: %d\n", num);
printf("Value accessed through const pointer: %d\n", *ptr);
- Finally, Arun should return 0 from the main function to indicate that the program has finished successfully.
return 0;
}
So, the complete program should look like this:
#include <stdio.h>
int main() {
int num;
printf("Enter an integer: ");
scanf("%d", &num);
const int *const ptr = #
printf("Original value of number: %d\n", num);
printf("Value accessed through const pointer: %d\n", *ptr);
return 0;
}
