(For thought) Although you have concentrated on operations involving integer and floatingpoint numbers, C++ allows adding and subtracting characters and integers. (These operations are possible with characters because they’re integer data types and are stored by using integer codes.) Therefore, characters and integers can be mixed in arithmetic expressions. For example, if your computer uses the ASCII code, the expression 'a'+1equals'b'and'z'1equals'y'.Similarly,'A'+1is'B'and'Z'-1is'Y'. With this information as background, determine the character results of the following expressions. (Assume all characters are stored by using ASCII codes.) a.m5b.m+5c.G+6d.G6e.baf.ga+1g.GA+1

-Program C 2. Not my Favorites by CodeChum Admin We've already done looping through a series of numbers and printing out its squares, so how about we level it up and go with cubes this time? I have a condition though; I don't want to be associated with numbers that are divisible by 3 or 5 so if an integer is divisible by either of the two, don't make their cube values appear on the screen, please. Care to fulfill my request? Instructions: Print out the cube values of the numbers ranging from 1 to 1000 (inclusive). However, if the number is divisible by either 3 or 5, do not include them in printing and proceed with the next numbers. Tip: When skipping through special values, make use of the keyword continue and put them inside a conditional statement. Output Multiple lines containing an integer. 1 8 64 343 512 . . .
-Program C 5. Even Out by CodeChum Admin You know, I was lying when I said the last time that numbers associated with 3 are my favorite, because the one I actually like the most in the world are even numbers! But to make things harder for you, you have to pick the even numbers from a range of two given numbers. Ha! Now, let's try this one more time! Instructions: Input two integers in one line, separated by a space. The first integer shall represent the starting point, and the other, the ending point. Print out all even numbers that are within the range of the starting and ending point (inclusive or including the ending point). Input 1. The starting point 2. The ending point Output The first line will contain a message prompt to input the starting point. The second line will contain a message prompt to input the ending point. The last line contains the integers within the range. Enter·the·starting·point:·5 Enter·the·ending·point:·10 6·8·10
