Which of the following is known as open-source?

[C++11]: Which of the statements a), b) and c) is false?

a. C++11’s header now contains functions for converting from numeric values to string objects and from string objects to numeric values. b. The to_string function returns the string representation of its numeric argument and is overloaded for types int, unsigned int, long, unsigned long, long long, unsigned long long, float, double and long double. c. Each C++11 function that converts a string to an integral type receives two parameters—a string containing the characters to convert and a pointer to a size_t variable where the function stores the index of the first character that was not converted (a null pointer, by default). d. All of the above statements are true.

In general, simple patterns are easy to create and complex patterns are more difficult.
