Write a C++ program to arrange 10 numbers in ascending order

Exercise 2)
Write a C++ program and call it sortcheck.cpp which receives 10 numbers from input and checks whether these numbers are in ascending order or not. You are not allowed to use arrays. You should not define more than three variables.

e.g    Welcome to the program written by Your Name:
Please enter 10 Numbers: 12 17 23 197 246 356 790 876 909 987
Fine, numbers are in ascending order.

Program to make simple calculator

Exercise 1)

Write a program and call it calc.cpp which is the basic calculator and receives three values from input via keyboard.

 The first value as an operator (Op1) should be a char type and one of (+, -, *, /, s) characters with the following meanings:

o ‘+’ for addition (num1 + num2)

o ‘-’ for subtraction (num1 - num2)

o ‘*’ for multiplication (num1 * num2)

o ‘/’ for division (num1 / num2)

o ‘s’ for swap

 Program should receive another two operands (Num1, Num2) which could be float or integer.

 The program should apply the first given operator (Op1) into the operands (Num1, Num2) and prints the relevant results with related messages in the screen.

 Swap operator exchanges the content (swap) of two variables, for this task you are not allowed to use any further variables (You should use just two variables to swap).
