C++ Exercise 1:</div>
<div style="background-color: white; color: #222222; font-family: Arial, Tahoma, Helvetica, FreeSans, sans-serif; font-size: 15px; line-height: 21px; margin: 0px;">
Write a program and call it calc.cpp which is the basic calculator and receives three values from input via keyboard.</div>
<div style="background-color: white; color: #222222; font-family: Arial, Tahoma, Helvetica, FreeSans, sans-serif; font-size: 15px; line-height: 21px; margin: 0px;">
 in this C++ tutorial The first value as an operator (Op1) should be a char type and one of (+, -, *, /, s) characters with the following meanings:</div>
<div style="background-color: white; color: #222222; font-family: Arial, Tahoma, Helvetica, FreeSans, sans-serif; font-size: 15px; line-height: 21px; margin: 0px;">
o ‘+’ for addition (num1 + num2)</div>
<div style="background-color: white; color: #222222; font-family: Arial, Tahoma, Helvetica, FreeSans, sans-serif; font-size: 15px; line-height: 21px; margin: 0px;">
o ‘-’ for subtraction (num1 - num2)</div>
<div style="background-color: white; color: #222222; font-family: Arial, Tahoma, Helvetica, FreeSans, sans-serif; font-size: 15px; line-height: 21px; margin: 0px;">
o ‘*’ for multiplication (num1 * num2)</div>
<div style="background-color: white; color: #222222; font-family: Arial, Tahoma, Helvetica, FreeSans, sans-serif; font-size: 15px; line-height: 21px; margin: 0px;">
o ‘/’ for division (num1 / num2)</div>
<div style="background-color: white; color: #222222; font-family: Arial, Tahoma, Helvetica, FreeSans, sans-serif; font-size: 15px; line-height: 21px; margin: 0px;">
o ‘s’ for swap</div>
<div style="background-color: white; color: #222222; font-family: Arial, Tahoma, Helvetica, FreeSans, sans-serif; font-size: 15px; line-height: 21px; margin: 0px;">
in this C++ tutorial Program should receive another two operands (Num1, Num2) which could be float or integer.</div>
<div style="background-color: white; color: #222222; font-family: Arial, Tahoma, Helvetica, FreeSans, sans-serif; font-size: 15px; line-height: 21px; margin: 0px;">
 in this C++ tutorial 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.</div>
<div style="background-color: white; color: #222222; font-family: Arial, Tahoma, Helvetica, FreeSans, sans-serif; font-size: 15px; line-height: 21px; margin: 0px;">
 in this C++ tutorial 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).</div>
