Help 'do while' loop

[Otto]

Does not like my while statement. Help
How to fix?

do
{

/* several statements all work correctly */

printf("Enter 'X' to exit program\n);
scanf( " %c", &option);
while (option != 'X' || option != 'x')
}

Sorry about the lack of tags.

That isn't the syntax for a do...while loop. First you have do, then a statement or compound statement, while, and a semicolon:

do
    statement
while (condition);

Your code (assuming you've omitted nothing important) should be:

do
{
    printf("Enter 'X' to exit program\n);
    scanf( " %c", &option);
}
while (option != 'X' || option != 'x');

Guys,

Shame on me. I guess I was tired etc.
Happens when trying a new language.
Thanks again.
