Write a Program to store city names and sort them in acceding order Using Dynamic Memory Allocation. To perform this program, allocate memory dynamically using malloc() function and before exiting the program we will release the memory allocated at run time by using free() function.

A monochrome screen is stored as a single array of bytes, allowing eight consecutivepixels to be stored in one byte. The screen has width w, where w is divisible by 8 (that is, no byte willbe split across rows). The height of the screen, of course, can be derived from the length of the arrayand the width. Implement a function that draws a horizontal line from ( xl, y) to ( x2, y).The method signature should look something like:drawline(byte[] screen, int width, int xl, int x2, int y)

Create a function append(v, a, n) that adds to the end of vector v a copy of all the elements of array a. For example, if v contains 1,2, 3, and a contains 4, 5, 6, then v will end up containing 1, 2, 3, 4, 5,6. The argument n is the size of the array. The argument v is a vector ofintegers and a is an array of integers. Write a test driver.
