Array Output

Question

I 'm trying to print someone's first initial of a middle name in my program
For example:
user input-John Henry Holiday
program output- Holiday, Henry H.

#include <iostream>
#include <string>

using namespace std;

string capitalize(string name);
string lastNameFirst(string name[]);

int main()
{
string userName[3];

cout << "First name: ";
getline(cin, userName[0]);

cout << "Middle name: ";
getline(cin, userName[1]);

cout << "Last name: ";
getline(cin, userName[2]);

cout << "Your name is: " << lastNameFirst(userName) << endl;
system("pause");
return 0;
}

string capitalize(string name)
{
int i = 0;
int isSpace = 0;

if (!name.empty())
{
name[0] = toupper(name[0]);
}

for (i = 1; i < name.length(); i++)
{
if (name[i] == ' ')
{
isSpace = 1;
}
else {
if (isSpace)
{
name[i] = toupper(name[i]);
isSpace = 0;
}
else
{
name[i] = tolower(name[i]);
}
}
}

return name;
}

string lastNameFirst(string name[])
{
string userName = capitalize(name[2]) + ", " +
capitalize(name[0]) + " " +
capitalize(name[1]);
return userName;
}

Answer 1

A few notes first;

● Explain your problem, it seems you haven't already.
● Does this code run? I tested it in Playground and it didn't ask for input.
● For "John Henry Holiday" isn't it supposedly "Holiday, John H" ??
● Attach a saved code URL instead of pasting a lengthy code snippet like this; in case you don't know how, please follow these steps:

» Create or open the code on SoloLearn editor. Don't forget to save any changes made.

» On mobile app, tap on Share button on the top right of editor → Copy to clipboard. Note you'll need to save the code before the Share button can be used.

» On web browser, copy code URL from browser's address bar.

» Edit the original post, remove the code snippet that's already there.

» On mobile app, long press on "Description" text input → Paste.

» On web browser, right click on "Description" text input → Paste.

Waiting on you ...

//If i understand correctly is this what you want to do?
#include <iostream>
#include <string>
#include <algorithm>
using namespace std;

string capitalize(string& name);
string lastNameFirst(string name[]);

int main()
{
string userName[3];

cout << "First name: ";
std::cin >> userName[0];

cout << "Middle name: ";
std::cin >> userName[1];

cout << "Last name: ";
std::cin >> userName[2];

cout << "Your name is: " << lastNameFirst(userName) << endl;
system("pause");
return 0;
}

string capitalize(string& name)
{
std::transform(name.begin(), name.end(), name.begin(), ::tolower);
name[0] = std::toupper(name[0]);
return name;
}

string lastNameFirst(string name[])
{
string userName = capitalize(name[2]) + ", " +
capitalize(name[0]) + " " +
capitalize(name[1])[0];
return userName;
}
