compiling is okay but my program doesn't really work - c++

Question

#include <iostream>
#include <string.h>
using namespace std;
int main()
{
while (1)
{
char name1[100];
char adrs1[100];
char rsn1[100];
char XXXXX[100];
cout << "input personal information" << '\n';
cout << "patient 1" << '\n';
cout << "input the name of the patient" << '\n';
cin.getline (name1,100);
cout << "input the address of the patient" << '\n';
cin.getline (adrs1,100);
cout << "input the reason" << '\n';
cin.getline (rsn1,100);
cout << "input the name of the patient" << '\n';
cout << "if you want to exit, input exit" << '\n';
cin.getline (XXXXX,100);
if (XXXXX==name1)
cout << adrs1[100] << rsn1[100] << '\n';
else (XXXXX=="exit");
break;
return 0;
}
}
that's my program, and compiling is okay. but when i start the program, it doesn't print any rsn or adrs, it just ends.
I want it to print rsn and adrs when it reads names.
Help me please

Answer 1

There are quite a few errors in your program.
The most important one is that you are trying to write an infinite loop. But it runs exactly once. You need to move your return statement out of the loop.
There is no need for a conditional statement for an else block. You can remove it along with the semi colon.
You're trying to print a character at the index 100 which goes out of bounds.
I don't know what XXXXX is supposed to be. May be you missed pasting the declaration on this website.
At this point, I really suggest picking up a book or trying to debug your code by going step-by-step through your code. It would be more helpful to you at this stage in your learning than this website,

To complete the answer above, the correct program would be:
#include <iostream>
#include <string.h>
using namespace std;
int main()
{
while (1)
{
char name1[100];
char adrs1[100];
char rsn1[100];
char XXXXX[100];
cout << "input personal information" << '\n';
cout << "patient 1" << '\n';
cout << "input the name of the patient" << '\n';
cin.getline (name1,100);
cout << "input the address of the patient" << '\n';
cin.getline (adrs1,100);
cout << "input the reason" << '\n';
cin.getline (rsn1,100);
cout << "input the name of the patient" << '\n';
cout << "if you want to exit, input exit" << '\n';
cin.getline (XXXXX,100);
if (strcmp(XXXXX,name1) == 0)
cout << adrs1 << rsn1 << '\n';
else /*(XXXXX=="exit");*/
break;
//return 0;
}
}

You forgot to initilize the name1 variable, you can initialize it using char name1[100] = {};
You cannot directly compare the if (XXXXX==name1), use can use the strncmp function for the same. I will prefer the string class instead of char pointer. Use the following:
if (!strncmp(XXXXX,name1,100))
cout << adrs1 << rsn1 << '\n';
else if (!strncmp(XXXXX,"exit",100))
break;
