Function parameter help

Question

I try many solution and I check the answer, but I don't know why my code doesn't work.

#include <iostream>
using namespace std;

void bot(int mode, string name){
if (mode==1){
cout<<"Welcome"<<name<< "!";
}
else if (mode==2){
cout << "Goodbye, "<<name<<"!";
}
else{
cout << "Try again";
}

}
int main() {
int mode;
cin >> mode;

string name;
cin >> name;

bot(mode, name);
}

Answer 1

side note, if you're allergic to #include for some reason, you can also use the plain C approach (he said evilly) of using char arrays.
(yeah, just #include <string>)

Answer 2

Look at cout<<“Welcome”<<name<<“!”;
When you concatenate welcome with name, you are not spliting the words. Example, if input is:
1 Steven
Output will be
WelcomeSteven!
You have to put an space after Welcome
That line of code should be like this:
cout << “Welcome “ << name << “!” << endl;
