Summary of Arduino serial functions related to print read

To sum up I'm learning arduino  srial Function time A few knowledge points of ：

/**
 *  Put it together Serial.print Some situations of output , The latter part should be connected with Serial.read In combination with ;
 * 1. print  The output characters   and int Number of results ,
 * 2. print  Output string and a series of numbers 
 * 3. read  Read a character   Then the output 
 * 4. read  Read a number   Then the output 
 * 5. How to read multiple numbers and then output 
 * 6. How to read multiple characters and then output

  Serial.println(intDazhengshu1,HEX); //  The integer form is normal output , If you don't take HEX ,  It defaults to decimal output , 
  Serial.println(intDazhengshu2,HEX); //  Pay attention here ,0X22221  More than the 16 position ,Arduino UNO  Maximum storage 16 position , exceed 16 position , Truncation occurs , You can see that one is missing in the output result 2

                            // When outputting    The output is this number , This code is displayed   Corresponding characters , 16  Corresponding characters   It's garbled

The operation results are as follows ：
