Introduction
For this challenge, we’re moving away from problems we can solve by a two-pointers approach and instead try something different.
Problem statement
You will have to implement the C library function strchr.
This function takes a string and a character as inputs. It returns a pointer to the first occurrence of the character in the string.
If the character doesn’t occur in the string, it returns NULL.
The function will look ...
