#includeThis code demonstrates different scenarios where SetLength function is used to change the size of a string, sometimes using a character to fill in the extra space. Package library: Standard string library (string.h)#include using namespace std; int main() { string myString = "hello"; cout << myString << endl; // Output: hello myString.resize(8); // Increase size to 8 cout << myString << endl; // Output: hello (with 3 trailing spaces) myString.resize(4); // Decrease size back to 4 cout << myString << endl; // Output: hell myString.resize(10, 'a'); // Increase size to 10 with 'a' character cout << myString << endl; // Output: hellaaaaaa }
