c: string entered not recognised

Question

Given below is a piece of code that does not do what I want

do
{
    printf("inserisci un nome: ");
    scanf("%29s", s);
} while (s!="*");

My aim is to exit from the cycle if the string entered is "*". Why doesn't it work? What should I modify?

Take a look at strcmp to compare strings, != will not do what you want.

In that case != will compare the variable s (a pointer to the first element of the array s) with the string "*". That is why it was not working properly.
