error: control reaches end of non-void function. What does this mean?

[rose echo]

Usually this means that a return has no value but how would i implement it in here?

[spiral plume]

the problem is that the convert function doesn't cover every possible value of char and in some cases may exit the function without returning a value

[rose echo]

how would you go about fixing the issue?

[mellow lagoon]

making a default option at the end

[rose echo]

ah so defaulting and then returning so that with an invalid input it defaults to what i choose it to be

[mellow lagoon]

yes

[rose echo]

thanks
