Exercise #3: Simple Calculator Write a C++ program that prompts the user to enter two integers and a symbol for one of the four arithmetical operators (+,-, *, /, %). The program then uses the switch statement to print the result of the arithmetical operation, otherwise the program displays the message "Invalid symbol". Sample input / output: Enter two integers: 5 9 nter the symbol of an arithmetical operator (+, -, *, /, %): + 5+9=14 Enter two integers: 59 Enter the symbol of an arithmetical operator (+, -, *, /, %): ^ ^ 9 = Invalid symbol
