I am a beginner in C++. And I am trying to play with character array in C++. So, I have written this code.
#include <iostream>
using namespace std;
//Main Function
int main()
{
//Variable declaration
char First[30];
char Middle[30];
char Last[40];
//Array to store all names
char Name[70];
//Loop variables
int i = 0, j = 0;
//Reading all the name
cout << "Enter First name: ";
cin >> First;
cout << "Enter Middle name: ";
cin >> Middle;
cout << "Enter Last name: ";
cin >> Last;
//Copies all characters of Last name to fourth array
while (Last[i] != '\0')
{
Name[j] = Last[i];
i++;
j++;
}
//placing a comma in the fourth array and adding a space
Name[j] = ',';
j++;
Name[j] = ' ';
j++;
cout<<"Hello1\n";
//Copies all characters of First name to fourth array
i = 0;
while (First[i] != '\0');
{
Name[j] = First[i];
i++;
j++;
}
//Add a space
Name[j] = ' ';
j++;
cout<<"Hello2\n";
//Copies all characters of Middle name to fourth array
i = 0;
while (Middle[i] != '\0');
{
Name[j] = Middle[i];
i++;
j++;
}
Name[j] = '\0';
//Display the fourth array
cout << Name << endl;
}
The Problem with this code is that i want to print the Full Name of
Name[] array. But it is getting stuck after printing "Hello1" only.
It is not printing anything after "Hello1". It is taking input of all
three names ( in First[] , Middle[] and Last[] ) correctly. So, I
decided to trace out my code from line 1. I got to know that there is
some problem after first while loop as i am trying to print "Hello1"
and "Hello2". The problem is that it is printing "Hello1" correctly
but it is getting stuck for "Hello2". I think that some problem is in
2nd while loop. But i am not getting the error how could i resolve
this.
Please help me regarding this so that it could print the Full Name
correctly.

Ok so, the problem is your while loop, you made the mistake of put a ; in the end of it, which is making an infinity loop and never gets to the second hello.
//Copies all characters of First name to fourth array
i = 0;
while (First[i] != '\0'); // <- Here is your problem
Should be:
//Copies all characters of First name to fourth array
i = 0;
while (First[i] != '\0') { // <- Here is your problem
Edit
Thanks to Gilles-Philippe Paillé who pointed out, in the third while loop also has an semi-colon which should be removed :D
