Strings: Copying in c
How might I write an implementation in C of the standard library function strstr? Here's how I might.
What if I need it to be case-insensitive? (View Snippet)
How might I write an implementation in C a case-insensitive version of the standard library function strstr? Here's how I might.
But I need it to be case-sensitive? (View Snippet)

Many times strtok is recommended for parsing a string; I don't care for strtok. Why?
It modifies the incoming string, so it cannot be used with string literals or other constant strings.
The identity of the delimiting character is lost.
It uses a static buffer while parsing, so it's not... (View Snippet)
Never use the function gets. Why? It is unsafe. Since the maximum string size cannot be specified, it is always susceptible to buffer overflow.
This snippet shows one way to do a safe version of gets. It reads characters from the stdin into a string up to the specified size and discards the... (View Snippet)
Obtaining user input can be done in many surprisingly different ways. This code is somewhere in the middle: safer than gets(text) or scanf("%s", text), but not bulletproof. It is meant to be a simple but relatively safe demonstration.
The function mygetline reads user input from the stdin into a... (View Snippet)
Obtaining user input can be done in many surprisingly different ways. This code is somewhere in the middle: safer than scanf("%d", &n), but not bulletproof. It is meant to be a simple but relatively safe demonstration.
The function mygeti reads user input from the stdin into a string using fgets.... (View Snippet)
This snippet shows how to use the functions time, localtime, and strftimetime to pick off only the time parts for display. (View Snippet)
