52. Getting Started with C++: Substring, Swapping and Finding
In C++, the string class offers several built-in functions that allow you to manipulate strings in various ways. In this video, we'll take a closer look at three commonly used string functions: substrings, swapping, and finding.
First, we'll explore substrings, which are a portion of a string. The substr() function can be used to extract a substring from a larger string. We'll see how to use this function to extract a portion of a string, and then use the extracted substring in other operations.
Next, we'll take a look at swapping, which allows us to exchange the values of two strings. The swap() function can be used to swap two strings, which is especially useful in sorting algorithms.
Finally, we'll examine finding, which allows us to locate a specific substring within a larger string. The find() function can be used to find a specific substring, and it can also be used to search for multiple occurrences of a substring within a string.
By the end of this video, you'll have a better understanding of how to use substrings, swapping, and finding in your C++ programs, and you'll be able to use these functions to manipulate strings in various ways.
