Question

i have the follwing code:

char* id = someFunction();
if (id == "0x01") {
    id = ....
}

so, what i basically need – is to check, if in the id variable i have the string value “0x01”, and if yes, then pass there the {0x01, 0x00} system symbols instead of it.

Thanks for your help.

Answer 1

use strcmp().

this function is available in string.h

Example:

printf( "Enter your name: " );
scanf( "%s", name );
if( strcmp( name, "Mary" ) == 0 )
  printf( "Hello, Dr. Mary!\n" );
