Counting the number of characters inside double quotation marks

Question

I want to find the number of characters inside a double quotation mark.

For example :

Case 1

\"Hello World\" , \"Some

output :

Answer 1

You could use something simple like finding the positions of the double quotes and subtracting them.

static const std::string example = "The \"comment\" is quoted.";
const std::string::size_type first_position = example.find('"');
const std::string::size_type second_position = example.find('"', second_position + 1);
const unsigned int character_quantity = second_position - first_position;

There are issues with the above code, such as checking if the double quotes exist, that the OP should implement.

This is one of many possible implementations.
