What does stack mean?

Answer 1

One who stacks rocks singly show strength in stressful situations that would cause others to relent. It also means to have the ability to portray peace energy to those who don't disturb the stones. Those who knock them down show little remorse &/or no value in others creativity, they tend to be negative & are not happy at good things others do.

Answer 2

stack overflow is when you've used up more memory for the stack than your program was supposed to use. In embedded systems you might only have 256 bytes for the stack, and if each function takes up 32 bytes then you can only have function calls 8 deep - function 1 calls function 2 who calls function 3 who calls function 4 .... who calls function 8 who calls function 9, but function 9 overwrites memory outside the stack. This might overwrite memory, code, etc

Many programmers make this mistake by calling function A that then calls function B, that then calls function C, that then calls function A. It might work most of the time, but just once the wrong input will cause it to go in that circle forever until the computer recognizes that the stack is overblown.
