The call stack display in the debugger shows the order in which functions have been called during the execution of the program. In addition the call stack shows the parameter values that have been passed to the called functions.

Typical uses:

1. If the debugger stops at a breakpoint, the call stack tells you how you got there.

2. If functions are being called recursively, then the call stack will show the recursive calls and any parameters passed. This is useful to see how far the recursion has progressed.
