Default
During the function definition, you can set default values for the last parameters. For example, you want to print the country the user is from, but if you don't have this information, there is a way to print the default value ("Canada"):
12345678910void myFunc(string name, string country = "Canada") { cout << name << " is from " << country << endl; } int main() { // Call the function to be executed myFunc("Ted", "USA"); myFunc("Robin"); return 0; }
Here by the second function call, we don’t know the country Robin is from, so the function myFunc() used the default value for the country - Canada.
