std::string(size_t , char ) constructor:

std::string(size_t, char) Constructor in C++

The std::string(size_t, char) constructor in C++ creates a string of length specified by the first argument, with each character initialized to the value specified by the second argument.

1. size_t: The first argument specifies the length of the string to be created.
2. char: The second argument specifies the character with which the string will be initialized.

The constructor initializes the string by repeating the character specified by the second argument the number of times specified by the first argument. For example, std::string(5, 'A') creates a string of length 5 with each character initialized to 'A'.
