6. Improve the stringToInteger function to convert an entire string of digits to a non- negative integer. For example, "345" should be converted to 345. ●くろまる ●くろまる 7. Improve your function to handle bad strings, i.e., ones that are not all digits. Start by declaring a constant of type int named INVALID_COORDINATE and give it a value of -1. Make it a global constant by putting it before the main function (and before the function prototype). You will return this constant from stringToInteger as an error value whenever the input string is bad. ●くろまる Hint: Use a loop to process the characters sequentially. Hint: You can use the .length () function to determine how many characters are in a string variable. A somewhat irrelevant example is: if(i =. Anything less than '0' or greater than '9' is not a digit. ●くろまる Reminder: If a function has a return type, it should always return a value. If the computer ever reaches the end of your function without a return statement, it will return an apparently random value (whatever is handy in memory) instead. This problem causes weird bugs. The easiest way to avoid this problem is make the last line of your function a return statement. 9. Improve your main function so there is at least one test on a bad string.
