The code added within the body will become the protected code. Try to access the element stored at index 2 (third element) of the vector named vec. This element doesn’t exist. WebDec 18, 2014 · The visual representation of control flow that is built upon basic blocks is called a control flow graph (CFG). A CFG is a directed graph that represents all of the possible execution paths through a piece of code. Basic blocks are used to form the vertices in a CFG, and edges are added to represent the flow of control between the basic blocks.

Weba maximal-length sequence of branch-free code. It begins with a labelled operation and ends with a branch, jump, or predicated operation. A control-flow graph ( cfg) models the flow of control between the basic blocks in a program. A cfg is a directed graph, G = ( N, E ). Each node n ∈ N corresponds to a basic block. WebNov 9, 2011 · Of course there comes a point in your nested try/catch statements where you just have to say enough is enough. I was making a case for nesting as opposed to sequential try/catch's, saying that there are situations where you only want the code inside the second try to execute if the first try falls over. – scooters coffee gray ga
