Exception Handling

anyone could tell me what I am making wrong with the code, because can't pass all of it, just pass 3 of the 4 question . You are making a program to manage user names. A valid username needs to be minimum 4, maximum 20 characters long. Create a program to take a string as input, check its length and output "Valid" if the name is valid, or "Invalid", if it is not. https://code.sololearn.com/ca15A17a7a77

#include <iostream> using namespace std; int main() { string name; cin >> name; try { if(name.size() >= 4 && name.size() <= 20 ){ cout << "Valid" << endl;; }else{ throw "Invalid"; } } catch(char const* x) { cout<< x; } return 0; } //Good Luck
