Write a C program that allocates memory using the malloc function for an array of size specified by the user at runtime. Assign pseudo-random double values to the array elements, then sort the array using the qsort function. Using the examples from the lecture, define a function that compares numbers of type double. Pass the function address to the qsort function. Use the free function to free up memory. Problem 2: Modify the source code of the program from Problem 1 to sort the string (character array). • When allocating memory to an array, be sure to add '\0' at the end of the array. Assign random letters from 'a' to 'z' to the array elements. • Print the array of characters using the printf("%s\n", arr)....; command. • When using the qsort function, remember that '\0' must remain at the end of the array. • Using the examples from the lecture, define a function that compares characters. • Use the free function to free up memory. ●
