So we can compose those functions to build our final getName function. The algorithm is: split by the colon and then get the first element of the given list. Let's build a first function: const first = (list) => list Just like cin stream stringstream allows you to read a string as a stream of words. To get the first element we can use the list operator. Method 1: Using stringstream API of C++ Prerequisite: stringstream API Stringstream object can be initialized using a string object, it automatically tokenizes strings on space char. For example, str.slice (1, 4) extracts the second character through the fourth character (characters indexed 1, 2, and 3 ). array.slice (from, until) From: Slice the array starting from an element index Until: Slice the array until another element index For example, I want to slice the first three elements from the array above. slice () extracts up to but not including inde圎nd. The slice ( ) method copies a given part of an array and returns that copied part as a new array. Changes to the text in one string do not affect the other string.
Example: splitByTilde("john smith~123 Street~Apt 4~New York~NY~12345") // Description slice () extracts the text from one string and returns a new string. So now we can use our specialized splitByTilde function. We want to make this "john smith~123 Street~Apt 4~New York~NY~12345" into this const split = (separator) => (text) => text.split(separator) So the first thing would be the split function. This string.split("~") gets things done.Īnother functional approach using curry and function composition.
