#include#include int main() { std::string str = "Hello World!"; std::string substr = str.fromFirstOccurrenceOf("World", false, true); std::cout << "Sub-string: " << substr << std::endl; return 0; }
Sub-string: World!
#include#include int main() { std::string str = "abcdefghijk"; std::string substr = str.fromFirstOccurrenceOf('d', true, false); std::cout << "Sub-string: " << substr << std::endl; return 0; }
Sub-string: defghijkIn this example, the substring `defghijk` is extracted from the original string `abcdefghijk` using the `fromFirstOccurrenceOf` function with the parameter `'d'`. The `true` parameter specifies that the search is case-sensitive, and the `false` parameter specifies that the search should not include the starting delimiter. Package/library: The cpp String library is not a standard library in C++, but it could refer to some existing string classes or utility libraries that provide similar functions. It is difficult to determine the exact package/library without more context.
