Hi this question is very broad.
SCENARIO -- I want to diagrammatically represent the functions of my class and how they call each other? The functions have a definite pattern and I want to do this to accommodate future changes such as adding a new functionality which will require to write a new function.
Eg:
function_1() ---> calls function_master()
function_2() ---> calls function_master()
If tomorrow function_3 is created then the makers should know that they need to make a call to function_master().
There are many such complex relationships.
The Real Question --> What I'm trying to achieve, does it have a name? like function mapping diagram. I know about class diagrams. I don't want to include them. I want detailed diagram of only functions calling each other.
Can you suggest some tools so that I can make it?
It is called a function call graph. A tool that may be used is doxygen
