Languages may have features for dealing specifically with empty strings (those containing no characters).
The task is to:
- Demonstrate how to assign an empty string to a variable.
- Demonstrate how to check that a string is empty.
- Demonstrate how to check that a string is not empty.
#include <string> // ... std::string str; // a string object for an empty string if (str.empty()) { ... } // to test if string is empty // we could also use the following if (str.length() == 0) { ... } if (str == "") { ... }
