An array is a sequence of data items that are of the same type, that can be indexed, and that are stored contiguously. Typically, an array is called a data structure used to represent a large number of homogeneous values. The elements of an array are accessed by the use of subscripts. Subscripts start from zero and runs until less than the size of the array. Arrays of all types are possible. including multi-dimensional arrays. Strings are just arrays of characters terminated by a special character called the null character. A typical array declaration allocates memory starting from a base address. The array name is in effect a constant pointer to this memory address. a) Write a complete C program that demonstrates usage of a one-dimensional array of integers. The program should declare an array of a specific size first, and then should ask user to specify values to be stored to the array. The program should finally display all values from the array to the screen for checking if the values are correctly stored or not. b) Improve the program written in part (a) to calculate the summation, average, minimum and maximum of all values entered by the user. c) Write a complete C program that demonstrates the usage of character strings. The program should declare an empty character array of specific size, and then ask user to enter a string to be stored in the array using a scanf function. The program should finally display the string entered to the screen for checking if the characters are correctly stored or not. d) Improve the program written in part (c) by calculating the string length and displaying it to the screen and also by making a copy of the string entered to another empty character array inside the main function and also displaying it to the screen.
