HI Aravind palanisamy

This is a C language question.

U is integer literal, it allows values of integer type to be used in expressions directly.

Below type variable can use suffix U:

unsigned int
unsigned long int
unsigned long long int

For more information, please search "integer literal" with search engine. You will know more.

Have a great day,
Jun Zhang
