string equality

[garishnikov]

so..i dont know how to test if two strings are equal. need something equivalent to ".equals()" in java, just in c.

this is the code:

char c[2];

do
{
//some code

scanf("%s", c);

if(c == "y")
{ cont = 1; } else { cont = 0; }

}
while(cont)

Thanks

[tt]if ( strcmp( c, "y" ) == 0 )[/tt]

Though if you're after just one letter, this is much quicker
[tt]if ( c[0] == 'y' )[/tt]

In your example, you can remove the if() altogether, and just go with assigning a boolean result
[tt]cont = strcmp( c, "y" ) == 0;[/tt]

BTW, if you wish to do a case-insensitive string comparision
you can use the POSIX strcasecmp() or strncasecmp()
functions.
