I want to convert a string to an int and I don’t mean ASCII codes.
For a quick run-down, we are passed in an equation as a string. We are to break it down, format it correctly and solve the linear equations. Now, in saying that, I’m not able to convert a string to an int.
I know that the string will be in either the format (-5) or (25) etc. so it’s definitely an int. But how do we extract that from a string?
One way I was thinking is running a for/while loop through the string, check for a digit, extract all the digits after that and then look to see if there was a leading ‘-‘, if there is, multiply the int by -1.
It seems a bit over complicated for such a small problem though. Any ideas?
