Question

I have global variable eg int NUM = 4;. When I attached to the working application with gdb – its hang. Now, I want to get value of NUM and change it. How to do this?

Maybe, possible examples for other data type like char[] and std::string ?

thanks

In gdb you should use

    print INT

to show the value of INT and

    set variable INT = value

to set INT equal to value.
In an array use

    set variable array_variable[element_index] = value

to set the element at index element_index in the array array_variable to value.
