user-input

Existing answers I've found are all based on from_str (such as Reading in user input from console once efficiently ), but apparently from_str(x) has changed into x.parse() in Rust 1.0. As a newbie, it's not obvious how the original solution should be adapted taking this change into account. As of Rust 1.0, what is the easiest way to get an integer input from the user? Michael Here is a version with all optional type annotations and error handling which may be useful for beginners like me: use std::io; fn main() { let mut input_text = String::new(); io::stdin() .read_line(&mut input_text)

so basically user enters a sequence from an scanner input. 12, 3, 4 , etc. It can be of any length long and it has to be integers. I want to convert the string input to an integer array. so int[0] would be 12 , int[1] would be 3 , etc. Any tips and ideas? I was thinking of implementing if charat(i) == ',' get the previous number(s) and parse them together and apply it to the current available slot in the array. But I'm not quite sure how to code that. Java Devil You could read the entire input line from scanner, then split the line by , then you have a String[] , parse each number into int[]

Im quite new to PHP, i was wondering what methods/preventions other programmers use to stop data being entered twice into a MySQL database when a user refreshes on the same page as a form? Obviouly it happens and i need a good way to stop this. Thanks, Ben I call this a golden rule of web programming: Never ever respond with a body to a POST-request. Always do the work, and then respond with a Location: header to redirect to the updated page so that browser requests it with GET. This way, refreshing will not do you any harm.
