char str[]=“hello how are you?”;
char *ptr=strtok(str," “);
cout<< ptr<<”\n";
ptr=strtok(str," ");
cout<< ptr<<"\n";
ptr=strtok(NULL," ");
cout<< ptr<<"\n";
Output:
hello
hello
Doubt: why does how does not get printed in this case?
at this point ptr is null
if u check if(ptr == NULL) cout <<“output me”;
the if statement would execute.
so nothing is being printed here.
