#include <iostream>
#include <string>
#include <cctype>

using namespace std;

int main ()
{
    int firstMiddleLast;
    string name = "Jim Anderson Smith ";
    int index;
    char ch;
    
    cout << "enter a name in the format First Middle Last: ";
    cin >> firstMiddleLast;
    index = name. find(' ');
    cout << "First Name: " << name.substr(0, index) << endl;
    name = name.substr(index+1, name.length()-1);
    index = name.find(' ');
    cout << "Middle Name: " << name.substr(0, index) << endl;
    name = name.substr(index+1, name.length()-1);
    cout << "Last Name: " << name << endl;
    ch = toupper(firstMiddleLast.at(0));
    firstMiddleLast = ch + firstMiddleLast.substr(1, name.length());
    cout << "Initial:" <<
         << firstMiddleLast << endl;
    system("pause");
}

This is my code and I've been struggling with this for a long time now. Can someone tell me what I am doing wrong, I'm working with C++ and I'm suppose to get the Initials to appear but i can't seem to be able to get it. I'm still unsure as to how to use string.at, which separates the characters i believe.

Reason for edit:: Added missing Code Tags, Please learn to use them.

First, please use code tags like it says everywhere including under the textbox you filled out to post your question.


Second, please edit your title. Can you imagine if all 500,000 users posted "I need help" ?? Can you please change it to something meaningful?

The std::string.at() provides access to individual characters in your string. Example:

#include <string>
#include <iostream>

using namespace std;

int main()
{
   std::string yourString = "This is your string";
   for(int i = 0; i < yourString.length(); ++i)
      cout << yourString.at(i) << endl;
   return 0;
}

Should printout each character on it's own line. Also note you could use array notation[] instead of at() to access the individual characters;

I think your main problem is that cin > name will stop reading after the first space, so there will never be a second word. Try: std::getline(cin, name);

Personally, I would do string.split on the space character.
That will yeild you an array of n words
The first character of each word is therfore the initials.
This then automatically adjusts to however they enter their name:
John Smith
John Q. Public
John Public Citizen
