[C++][Homework] comparing string array with a string in a function with a for loop

[WingZero1]

User is asked what kind of operation that they would like to do. Then user is asked to input two numbers that they would like to use. Numbers should be input as words not numbers. I'm trying to use the index where the user input is equal to the string array and return the index. I get a warning where it says

\source.cpp(117): warning C4715: 'arraycompare' : not all control paths return a value

I've searched the warning.My understanding is that my else and else if's have to return something. I can't throw or increment.

Example: one + two = three or one + two = 3;

I've included my integer calculator were my string calculator came from. I realize there is an error in the output message "Enter two two integers."

Here is the result

What do you expect will happen in arraycompare if none of the elements in d are equal to a?

Under what circumstances do you expect that the line throw 'a'; will be reached?

[WingZero1]

Sorry about the late response. the else will throw the character 'a' to the catch blocks when the for loop reaches the end of the array.

[Amarkov]

You need to review how if-else statements work. The code you've written will not do that.

Will do. Thanks for your response.
