Create an aligned malloc and free code that allows you to allocate memory in such a way that the memory location returned is divisible by a power of two. EXAMPLE align_malloc (1000, 128) will yield a memory address that is a multiple of 128 and refers to 1000-byte memory. aligned_free() releases memory that was created by align_malloc.

- c programming language The program below uses pointer arithmetic to determine the size of a 'char'variable. By using pointer arithmetic we can find out the value of 'cp' and thevalue of 'cp+1'. Since cp is a pointer, this addition involves pointer arithmetic:adding one to a pointer makes the pointer point to the next element of the sametype.For a pointer to a char, adding 1 really just means adding 1 to the address, butthis is only because each char is 1 byte.1. Compile and run the program and see what it does.2. Write some code that does pointer arithmetic with a pointer to an int anddetermine how big an int is.3. Same idea – figure out how big a double is, by using pointer arithmetic andprinting out the value of the pointer before and after adding 1.4. What should happen if you added 2 to the pointers from exercises 1through 3, instead of 1? Use your program to verify your answer.#include <stdio.h>int main( ){ char c = 'Z'; char *cp = &c; printf("cp is %p\n", cp);…Program this in java the state and variable display must be:Unsorted Partition Reference Index: 0, Traversing Index: 7, Current Traversing Index Value: mango, Next Index Value: plum, Swapping Condition: FalseCurrent Array: ['apple', 'avocado', 'orange', 'banana', 'strawberry', 'pineapple', 'plum', 'mango'] The input:["apple", "avocado", "orange", "banana", "strawberry", "pineapple", "plum", "mango"]Note:The sorted partition is on the left side. Then, the order is increasing based on the number of vowels of a string.the output must be like this:['plum', 'apple', 'strawberry', 'mango', 'orange', 'banana', 'avocado', 'pineapple']Please answer the below question for operating system using shell script. write a program in bash that has a user_defined function array_sum that takes each element of array as argument andcalculates their sum.

After that use that pointer to access the array and store on it the powers of two then display the content of the array on the screen. The output should be: 2 4 6 8 16 32 128 256 512 1024. Note: You can use the pow() function. This function takes two arguements and returns the result of the first argument raised to the power of the second arguement.a) Write the definition of a subroutine that swaps the first and the last members of an array of 10double-words. Note that the array is pointed by SI. b) Write the definition of another subroutine, which multiplies the least significant nibble and themost significant nibble of AX register. The result is to be saved into AL.
- 1. Refactor your bookType ADT that you created in Module 1B. You will need to update the implementation of your ADT by: Making the authors attribute a dynamic array and ensuring any affected code is updated to handle the new type. Adding a destructor 2.

Use malloc and free. Fill the array, print the elements and calculate the average value. A. In the main function: a) Ask the user for the size of the array. b) Using the malloc function allocate the double array of the size specified by the user. c) Check if the allocation was successful. - If the address returned by malloc is not NULL, use the rand function in a for loop and assign pseudorandom values to the array elements. Then call the function averagevalue. Print the result. Free up memory with the free function. - If the allocation failed and the address returned by malloc is NULL, print the message and exit the program. B. Define the function averagevalue and then call it in main. The function calculates the average value of the elements of the array passed as an argument and prints the array elements to the screen. The function returns the average value. C. Use…
