Recap - Simple Calculator
Part of the Fundamentals section of Coddy's Swift journey — lesson 28 of 86.
Challenge
Easycalculate that takes a, b, and operation and returns the result of the mathematical operation.
Based on the operator symbol, perform the corresponding calculation on the two numbers.
Supported Operations:
"+"- return the sum of a and b"-"- return the difference (a minus b)"*"- return the product of a and b"/"- return the quotient (a divided by b, integer division)- Any other operation - return
0
Parameters:
a(Int): The first numberb(Int): The second numberoperation(String): The operator symbol
Returns: The result of the calculation, or 0 for unknown operations (Int)
Try it yourself
func calculate(a: Int, b: Int, operation: String) -> Int {
// Write code here
}
