Int strcm (const char * str3, const char * str4)
{
For (; * str3 == * STR4; STR3 , STR4 )
IF (! * STR3) --------- "
Return 0;
Return (* STR3- * STR4); ----------- "
}
I would like to ask: (! * Str3) Is it that the address of STR3 is not 0?
* STR3- * STR4 does not indicate the comparison of two character addresses? Otherwise how can two characters can be subtracted? ?
