watch value 'inside' adress when debugging?

[Stauricus]

hello everybody

is it possible, when debugging, to watch a value pointed by a pointer? i mean, to see what is inside that adress?
in this picture, pi shows 0x7fffffffe714. is it possible to see the value 10 trough pi?


i searched about it, and found some people saying to dereference the pointers. but do they mean dereferencing in the actual code? do i have to make it to all pointer variables that i want to see "inside"? 

i hope i was able to explain the issue...  :-\
thanks for the help!

Add pi as a watch and right click dereference or just add *pi as a watch.

thanks, it works! but and in this another situation, using arrays, is it also possible? it doesn't seems to work to me, since  no "dereference" option shows up.

Code Select Expand

int main(){
    int i = 10;
    int* n[1] = {&i};

    return 0;
}

For arrays you have to right click on the watch -> properties -> mark it as array and specify a size.

it did not work in the case... no "dereference" option yet.
but if i add **pi as a watch, it shows the value. i didn't knew i could add the variable names manually in the watch window before your answers 
thank you!


EDIT: ok, no just one more problem. how to watch multidimensional arrays of pointers?
up to now, i'm like this:





but i'm not able to see the values, just adresses.

thanks again!


EDIT AGAIN:
omg, i feel stupid. i didn't knew i could add things like *p[1][1] and *0x5555555a46b0 to the watch screen. problems solved!
thank you very much!

just for reference:
Nearly every valid c/c++ expression can be entered in the watches window, also function calls (but be aware, they may crash your application if called in the wrong context and with it also gdb!)
