The document is a student paper about control flow based design. It introduces control flow graphs, which graphically represent the flow of a program during execution. Control flow graphs are used in static analysis and by compilers. They show all possible paths through a program. The document discusses that control flow graphs are process oriented, directed graphs. Their nodes represent basic blocks and edges represent control flow paths. It also outlines that control flow graphs contain entry and exit blocks.

2. INTRODUCTION-
A Control Flow design is the graphical representation
of control flow or computation during the execution of
programs or applications. Control flow graphs are
mostly used in static analysis as well as compiler
applications, as they can accurately represent the flow
inside of a program unit. The control flow graph was
originally developed by Frances E. Allen.

3. DISCUSSION
Characteristics of Control Flow Graph:
•Control flow graph is process oriented.
•Control flow graph shows all the paths that can be
traversed during a program execution.
•Control flow graph is a directed graph.
•Edges in CFG portray control flow paths and the nodes
in CFG portray basic blocks.

4. There exist 2 designated blocks in Control Flow
Graph:
1.Entry Block:
Entry block allows the control to enter into the
control flow graph.
2.Exit Block:
Control flow leaves through the exit block.
