C++ cstring Library

C++ cstring Functions

The <cstring> library has many functions that allow you to perform tasks on arrays and C-style strings.

Note that C-style strings are different than regular strings. A C-style string is an array of characters, created with the char type. To learn more about C-style strings.

C++ Iterator

C++ Iterators

Iterators are used to access and iterate through elements of data structures (vectors, sets, etc.), by “pointing” to them.

It is called an “iterator” because “iterating” is the technical term for looping.

To iterate through a vector, look at the following example:

Example

// Create a vector called cars that will store strings
vector<string> cars = {"Volvo", "BMW", "Ford", "Mazda"};

// Create a vector iterator called it
vector<string>::iterator it;

// Loop through the vector with the iterator
for (it = cars.begin(); it != cars.end(); ++it) {
  cout << *it << "\n";
}
