using C programming

1.Write a function that will reverse the order of the elements of an array of int variables. In the main()

function declare an 8-element integer array, then have the user enter the value of each element using a

loop. The program should then call the other function to reverse the order of the elements in the array, and

then print the values of the resulting array to the screen.

2.

Write a program to input a string from the user use a loop and the getchar() function (similar to the

capitalize.c example program we looked at in class). The program should then convert the string to all

lowercase letters, and put each word on its own line. Print the new string.

Example:

Enter a string: This Is A STRING.

this

is

a

string.

3)Write a program that will ask the user to enter an integer. The program should check if the 3rd least

significant bit of the number (in binary) is a '1' or '0', and tell the user. If the bit was a '0' the program should

set the bit to '1'; if the bit was a '1' it should clear the bit to zero. The program should then display the new

resulting integer number.

4)Write a program that will determine the number of bits required to represent a positive integer. The

program should have the user enter a decimal integer, then use a loop with a bitwise operator to determine

the number of bits in its binary representation. For example, if the user entered 18 (which in binary is

10010) the program should indicate 5 bits. (Hint: start at the highest order bit and look for the first '1').

Example:

Enter a positive integer: 18

Number of bits: 5
