#includeusing namespace mozilla; int main() { nsAutoString str1("hello"); if (str1.IsEmpty()) { printf("String is empty\n"); } else { printf("String is not empty\n"); } return 0; }
#includeIn this example, we create a nsAString object named str2 with an empty string value. We then use the IsEmpty method to check if the string is empty or not. Since the string is empty, the if statement is executed and "String is empty" is printed. The nsAString IsEmpty method is part of the Mozilla's Gecko SDK package library.using namespace mozilla; int main() { nsAString str2(""); if (str2.IsEmpty()) { printf("String is empty\n"); } else { printf("String is not empty\n"); } return 0; }
