when using CIN
How do i make it so user input can be 5 or 6 letters
and
how do i put input into an if else statement ?
Example, i want the user to be able to input a word then program to decide
what word to spit out.

char input;
cout<<"Hi ";
cin>>input
if (input= = "Hello" ){
cout<<"Hello\n";
}
else{
cout<<"goodbye\n";
}
?

Your tring to compare two different spaces in th memory, they are not equal.
and you have forgotten to use an array of chars. This will work:

// Make space for more then one character, like this
char input[10];       // For a maximum of 10 characters

cout << "Hi ";
cin >> input;             // don't forget to end your input with ;

// Use a funtion called strcmp (String Compare)
// This returns zero if the two strings are equal
if (strcmp(input,"Hello")==0 ){
    cout<<"Hello\n";
}
else{
    cout<<"goodbye\n";
}
