Fundamentals of Object-Oriented Programming - C++ - String Methods

This video tutorial covers various string functions in programming, including size, append, insert, replace, and erase methods. It demonstrates how to join strings using the plus operator and append method, insert words at specific positions, replace characters, and erase parts of a string. Additionally, it explains how to create a find and replace function to modify strings by replacing spaces with symbols. The tutorial provides practical examples and error handling tips to enhance understanding of string manipulation techniques.

What does the size method return when applied to a string?

• The number of sentences in the string

• The number of characters in the string, including spaces

• The number of vowels in the string

• The number of words in the string

Which operator can be used to concatenate two strings?

• The minus operator

• The division operator

• The multiplication operator

• The plus operator

What is a key difference between using the plus operator and the append method for string concatenation?

• The append method automatically adds a space between strings

• The plus operator cannot add spaces between strings

• The append method is faster than the plus operator

• The plus operator can add spaces between strings

How can you insert a word at the beginning of a string?

• Using the erase method

• Using the size method

• Using the insert method

• Using the append method

What does the replace method do in a string?

• It removes all spaces from the string

• It changes a specified character or substring to another

• It adds a character at the end of the string

• It duplicates the string

What is the purpose of the erase method in string manipulation?

• To replace characters in a string

• To add characters to a string

• To find the length of a string

• To remove a specified part of a string

In the find and replace function, what is the role of the find method?

• To locate the first occurrence of a specified character

• To append a character to the string

• To count the number of spaces in a string

• To replace all characters in a string
