Basic C++ Problems

I'm having basic C++ problems. What's the problem? I'll do a direct copy+paste from Command Prompt.

Code:

Hello, please input your username:

Username:Test //I typed this in







Welcome! Please choose a category to enter.









 Cat01

 Cat02



// Does not prompt me to type anything in and just shows the following message.



Welcome to Cat1

Source:

Code:

#include &lt;iostream.h>



int main ()

{

  cout &lt;&lt; "Hello, please input your name: \nName:";

  int name;

  cin >> name;

  cout &lt;&lt; "\n \n \n";

  cout &lt;&lt; "Welcome! Please choose a category to enter. \n  \n  \n  \n  \n Cat01 \n Cat02 \n \n";

  int cat;

  cin >> cat;

  if (cat == 1)

  then

  cout &lt;&lt; "Welcome to Cat1";

  if (cat == 2)

  then

  cout &lt;&lt; "Welcome to Cat2";

}

Can anyone tell me what I'm doing wrong?

int -> integer, this is a number, not a char string.
name will never contain 'Test'.

After than check the if syntax :)

Soo.... what do I use instead of int?

char name[12];
for example

if (cat==1) {
}

instead of
if (cat==1) then

Revised:

Code:

#include &lt;iostream.h>



int main ()

{

  cout &lt;&lt; "Hello, please input your name: \nName:";

  char name;

  cin >> name;

  cout &lt;&lt; "\n \n \n";

  cout &lt;&lt; "Welcome! Please choose a category to enter. \n  \n  \n  \n  \n Cat01 \n Cat02 \n \n";

  char cat;

  cin >> cat;

  if (cat==1)

  cout &lt;&lt; "Welcome to Cat1";

  if (cat==2)

  cout &lt;&lt; "Welcome to Cat2";

  return 1;

}

It now asks for the input. BUT it does not say "Welcome to Cat#"

keep cat as an int if you make your tests like that " if (cat==1) "
1 is an int
'1' is a char

Muuss is right.

You made cat a type char so the compare should be:

Code:

 if (cat=='1') 

  cout &lt;&lt; "Welcome to Cat1"; 

  if (cat=='2') 

  cout &lt;&lt; "Welcome to Cat2";

Otherwise you are testing for ctrl+A or ctrl+B.

How to read a string properly in C++.

Code:

#include &lt;iostream>

#include &lt;string>



using namespace std;



int main()

{

   string name; 

   getline(cin, name);

   cout &lt;&lt; name &lt;&lt; "\n";

}
