C Programming: PRIu32 Format Specifier for Unsigned Integers

PRIu32 is a format specifier used in C programming language for printing unsigned 32-bit integers. It is defined in the 'inttypes.h' header file and is a part of the C standard library. The 'u' in PRIu32 stands for 'unsigned' and the '32' indicates the number of bits in the integer. It can be used with the printf() and scanf() functions to read and write unsigned 32-bit integers.
