. Write a program to find out your machine unsigned int, can store the data type of the largest integer and the largest integer bit digits, and print them out, how to do? Head.

CodePudding user response:

Largest integer: 0 can be as a complementation,
Bit: after the sizeof by 8

Upstairs, you are right
