Code:

#include <iostream>
#include <string>
using namespace std;

void main()
{
string name;
cout << "Enter your Full Name: " << endl;
getline(cin, name);
cout << endl;

}

I'd like to display a message saying "Please enter a valid Input" when the user inputs any value other than alphabets.

Make a function to loop through the input string and check each char to see if it's a valid character or not. If you want I'll post code tomorrow, I'm busy tonight.

LEAF you da best. By the way after this week is over I need to catch up with you man.

Yo just remembered this topic and threw this together hopefully its what you were looking for. it just compares each character to see if its a space or letter(upper and lowercase);

Code:

#include <iostream>
#include <string>
using namespace std;

bool ifValidName(string s)
{
    for(i=0;i<s.size();i++)
    {
        int asciicode =s[i];// convert char to ascii int value
        if(asciicode == 32 || (asciicode >=65 && asciicode<=90) || (asciicode >=97 && asciicode<=122));
        else return false;// if its not a space or letter return false
    }
    return true;
}
void main()
{
    string name;
    cout << "Enter your Full Name: " << endl;
    getline(cin, name);
    if(ifValidName(name)) cout << "real name" <<endl;
    else cout << "enter a valid input you noob" << endl;
    cout << endl;
    system("Pause");
}

If you want it to keep asking for the name until you get a valid one you can use goto statements(although some instructors dislike them) or a while loop. Idk if you've gone over functions yet. If not, I could modify the code to handle all of it in the main function.

I've done functions, but only the basic (to my knowledge). Thanks for the code. Is there a way to do it without converting it to an ascii value?

Have you gone over functions that return a value, or just void functions? If it's just void you can put the cout in the function where the return is and change it to a void. And yea you can do it without ascii but you'd have to have a switch or if statement for every upper and lowercase letter. The ASCII way is just less code but you can do it however you want.

Oh k thanx man. I've done functions that return a value, yep. Parameters and stuff. Thanx agin!
