Open address output, when the program displays the function information, GDB will show the function's parameter address. The system is turned on by default,
Show print Address
See if the current address display option is turned on.

Set Print array
Set Print array on
Open the array display, open when the array is displayed, each element occupies a row, if not open, each element is separated by commas. This option is off by default. The two commands associated with it are as follows, and I will not say more.

Set Print array off
Show Print Array

Set Print elements
This option is mainly set to the array, if your array is too large, then you can specify one to specify the maximum length of the data display, when the length is reached, GDB will not show down. If set to 0, no limit is expressed.

Show print elements
View option information for print elements.

Set Print Null-stop
If this option is turned on, a terminator is stopped when the string is displayed. This option is off by default.

Set Print pretty on
If you turn on printf pretty this option, it will be pretty when GDB displays the struct body.
