You will prompt the user for and read in an integer between 0 and 25, inclusivel

Question

You will prompt the user for and read in an integer between 0 and 25, inclusively. If the integer is not in range, you will display a meaningful message indicating it is either less than 0 or greater than 25, and then continually re-prompt the user to enter the integer again until the user enters a valid integer.

• Once the user has entered a valid integer, you will then prompt the user for and read in a second integer between –15 and 30, inclusively. If this second integer is not in range, you will display a meaningful message indicating it is either less than –15 or greater than 30, and then continually re-prompt the user to enter the integer again until the user enters a valid integer.

• Once both integers have been entered, you will prompt the user for and read in the arithmetic operation that the user wishes to perform as follows: addition (+), subtraction (–), multiplication (*), division (/), or modulus (%). If the user enters an operation other than those listed, you will display a meaningful message indicating that the operation is invalid, and then exit the program (i.e., not perform the requested operation).

• You will then perform the requested arithmetic operation as input by the user, showing the details of the operation (i.e., the actual operation being performed). Additionally, you will display a meaningful message indicating whether the result of the operation was negative, zero, or positive. • Your code should be well documented in terms of comments. For example, good comments in general consist of a header (with your name, course section, date, and brief description), comments for each variable, and commented blocks of code.

Example of OutPut

Enter an integer between 0 and 25, inclusively: 16 Now enter a second integer between -15 and 30, inclusively: -4 Enter the arithmetic operation (+, -, *, /, or %) you'd like to perform : * Multiplicatin: 16 * -4 = -64 The result of the operation (-64) is negative! mat0299@faculty:~/csce1030S ./a.out mat0299@faculty:/csce1030s ./a.out
