8. Write a C program function that uses pointers to swap to numbers.

8. Write a C program function that uses pointers to swap to numbers. 6. Write a C program that prints the English alphabet using pointers. 10. Write a C program void function that uses pointers to perform decompose operation. (Print only in the main function). Decompose means breaking up a decimal number into an integer part and a double part and storing them in different variables. 1. Write a C program function called ‘changeEven’ that changes all the even numbers within an array to 0, using pointer arithmetic 2. Write a C program function called ‘changePrime’, that changes all the prime numbers within an array to 0. Use another function, within ‘changePrime, called ‘checkPrime’, to check and return whether the number is prime or not, then update the value in the ‘changePrime’ accordingly. Don’t use pointer arithmetic 3. Write a C program that sorts an Array in descending order. 4. Write a C program function called ‘factorial’ that calculates and returns the factorial of a number. 5. Write a C program that gets an Array with 10 3-digits integer IDs. The program then prompts the user to enter his ID, which will be compared to the existing IDs within our Array. If his ID is matched, print “Accepted”, else print “Unaccepted”. 7. Write a C program that accepts three integers: a, b, and c, and prints them in ascending order 9. After the holidays lots of people were rushing to move back to their apartments. In this scenario, even numbers will represent women while odd numbers will represent men. Store the sequence of entry into the building by typing in even and odd numbers into an array at random. Calculate the largest sequence of women entering the building before a man enters. (The largest continuous number of women that entered before a man came in) Example: 17, 4, 6, 8, 9, 2, 8, 49 (The largest continuous number of women is 3).
