Can you explain typecasting here?

#1

in this video sir converted string to char by
(char*)str.c_str();
please explain me the complete meaning of this

#2

Hey @sid.rajput23 c_str function converts c++ string(which is essentially a null terminated array of bytes) to const char * but strtok wants char * ,So what we are doing is explicitly typecasting const char * to char *

#3

can you elaborate with example?
i think you are saying that by ““c_str”” we can convert string str to a CONSTANT char type pointer
and
by typing (char*) in front of it makes it to a char pointer

#4

Yes i mean this

so if you will not typecast it, it will give us an error.
