#include#include using namespace std; int main() { StringBuilder sb; sb.append("Hello "); sb.append("world!"); cout << sb.toString() << endl; return 0; }
#includeIn this example, we create a StringBuilder object and append a string to it. We then insert another string at the 6th position (after the "o") and append a third string. The resulting string is then printed to the console. Overall, the StringBuilder is a powerful and useful tool for manipulating strings in C++, and is essential for any programmer working with text-based data.#include using namespace std; int main() { StringBuilder sb; sb.append("Hello "); sb.insert(6, "big "); sb.append("world!"); cout << sb.toString() << endl; return 0; }
