gdb - check changed variables' values on next step

is there a way to check the value of lvalue variables without using the print command when debugging the code step by step, what I'm looking to do is the following:

If I have the following code:

> x = 5;
  y = 6;

when I'm debugging the code and I use next, I want gdb to display the value of x, that is the variable that changed in that instruction, I know I can watch the variable, but what I'm looking for is to be able to check variables on the fly without using print

is this possible?

You can use the display command:

(gdb) help display
Print value of expression EXP each time the program stops.

For instance if you display both you will get:

(gdb) next
4       y=6;
2: y = 0
1: x = 5
(gdb) 
5       return 0;
2: y = 6
1: x = 5
