AI Thread Summary
To search for a substring within a string in C and count its occurrences, the function `strstr` can be utilized. This function locates the first instance of the substring. To count all occurrences, repeatedly call `strstr` by updating the starting position to just after the last found instance until no more instances are found. While `substr` is relevant in C++, in C, `strstr` is the correct function to use for this task.

Yeah, messed that up...in C++ you would use string.find and string.substr, but in C you have strstr.

This seems to be a very elegant way of transmitting a message publicly that only the sender and receiver can decipher. Is this how PKE works? No, it cant be. In the above case, the requester knows the target's "secret" key - because they have his ID, and therefore knows his birthdate.

Thread 'Project Documentation'

Trying to package up a small bank account manager project that I have been tempering on for a while. One that is certainly worth something to me. Although I have created methods to whip up quick documents with all fields and properties. I would like something better to reference in order to express the mechanical functions. It is unclear to me about any standardized format for code documentation that exists. I have tried object orientated diagrams with shapes to try and express the...
