A palindrome is a word spelled the same way backwards and forwards. For example, Anna, radar, madam and racecar are all palindromes. Certain words can be turned into palindromes when the first letter is removed and added at the back, e.g. 'potato' will read the same backwards if we remove the 'p' and add it at the back, i.e. 'otatop' read backwards will still say 'potato'. Similarly, 'banana' when you remove the 'b' and add it at the back so that it becomes 'ananab' will still say 'banana' if you read it backwards. Write a program that reads a word into a C-string (a character array). The program should then determine whether the word would be a palindrome if we remove the first character and add it at the back of the word. Use only C-string functions and C-strings. Assume that we will not work with words longer than 20 characters. Hint: You may consider using the C-string function strrev () but it is not compulsory. Remember to plan your program!

Write a program that prompts the user to enter apoint (x, y) and checks whether the point is within the rectangle centred at (1, 1)with width 10 and height 5. For example, (2, 2) is inside the rectangle and (6, 4)is outside the rectangle, as shown in Figure . (Hint: A point is in the rectangleif its horizontal distance to (0, 0) is less than or equal to 10 / 2 and its verticaldistance to (0, 0) is less than or equal to 5.0 / 2. Test your program to cover allcases.) Here are two sample runs. Enter a point with two coordinates: 2 2 ↵EnterPoint (2.0, 2.0) is in the rectangle

When we say arithmetic expression, we mean a kind of expression you can type in a very basic desk calculator. That is, neither variables nor brackets are allowed. It contains only numbers and four arithmetic operators, +, -, *, and /.   The following are some examples of arithmetic expression:   Any number string with or without signs - e.g. 3, -1, +10, 3.14, -0.70 and 099. Number strings mixed with arithmetic operators - e.g. 3+5, -1+2*3, 7/10-0.7, and -1.4-+8.2.   An example of FA diagram for recognising a non-negative integer is given below. You may use it as a start point. You need to add a few more states and transitions to handle numbers with decimal point and signs (e.g. -5, +2, 0.21, -32.6, +99.05, but not the form 1.0E-3). Most importantly, you also need to add a few more things to deal with the arithmetic operators +, -, *, /.

This method returns a string where a triangle appears on the left size of the diagram, followed by horizontal lines. For example calling DrawingApp.getFlag(9, ‘R’, ‘.’, ‘Y’); will generate the string
