C Language

1. Write a C program that reads 10 integers and stores them in an array. The program should use qsort() to sort the array in ascending order. Then, the program should read an integer and use bsearch() to check if it is stored in the array.

2.Define the structure type coord with members the coordinates of a point (e.g., x and y). Define the structure type rectangle with members two structures of typecoord (e.g., point_A and point_B). Write a function that takes as parameters the two endpoints of a rectangles diagonal. Each endpoint should be a structure of typecoord. The function should calculate and return the area of the rectangle. Write a C program that uses the type rectangle to read the coordinates of the diagonal of the rectangle and uses the function to display its area.
