Splitting Strings by Multiple Delimiters
In the realm of string manipulation, effortlessly dividing a given text into discernible words is a common endeavor. When faced with a single delimiter, the problem is readily solvable using the tried-and-tested method of utilizing a stringstream and extracting substrings. However, when the task entails recognizing multiple delimiters, a different approach is required.
Assume that among the multiple delimiters is the newline character. In this scenario, the solution involves reading the line in its entirety and then further splitting it based on the additional delimiters. In the given code example, the focus is on identifying and extracting words bounded by spaces, apostrophes, and semi-colons.
The code commences by utilizing a stringstream object to traverse the input string. It proceeds to read lines one by one and for each line, initiates an iterative process. Within this iterative loop, it utilizes the find_first_of() function to locate the position of any of the specified delimiters within the line. If such a delimiter is found, the substring up to that point is extracted and added to a vector of words. This process continues until the end of the line is reached, at which point any remaining text is added to the word vector.
By embracing this approach, you empower your program with the ability to efficiently split a given string into meaningful words, even in the presence of multiple delimiters.
