Practice Project 1: Simple Calculator

Build a Simple Calculator

Time to apply what you've learned! Create a calculator that takes two numbers and an operator, then performs the calculation.

YOUR TASK

Create a program that:

Asks for the first number
Asks for an operator (+, -, *, /)
Asks for the second number
Calculates and displays the result

Need a hint?

Step-by-step:
1. Declare double num1, num2, result;
2. Declare char op; for the operator
3. Use cout to ask for input
4. Use cin to get input
5. Use if-else statements to check which operator:
- If op == '+' then result = num1 + num2;
- Same for -, *, /
6. Display the result

Example (if input is 10, +, 5):

Enter first number: 10
Enter operator (+, -, *, /): +
Enter second number: 5
Result: 15
