Question:
If a string is stored at the memory address 0 times 20008000 and the string is "Cortex-M", show the memory content in hex format starting at 0 times 20008000.
How many bytes does this string take in the memory?
Write a C program that implements the standard function char * strrchr (const char *str, int c) that returns the memory address of the last instance of c in string str.
Return a NULL pointer if c is not found in the string.
