I'm trying to figure out way to send some amount of text from the string ech time until it reach the end of the string, example:

const char* the_string = "hello world, i'm happy to meet you all. Let be friends or maybe more, but nothing less"

Output: hello world

Output: , i'm happy to meet you all.

Output: Let be friends or maybe more

Output: , but nothing less

stop: no more bytes to send.

the problem i have searched google, but didn't understand the examples, i spent 4 days trying find a good way, also that sendt 5 bytes at time, but in case there is less, then send them until you are at the end of the string.

please help me out guys, i will accept a C or C++ way, as long it works and well explained.
