The C function f() is declared within the notation extern “C” to tell the cpp compiler that it has C type linkage. Now, compile the code (make sure that the shared library libCfile.so is linked to the code): $ g++ -L/home/himanshu/practice/ -Wall main.cpp -o main -lCfile Bef...
Let’s now look at some examples, to understand this function better. We’ll also be usingfork()along withexecvp(), so that we can still have our C program with us! Using execvp() in C / C++ - Some Examples If you want to see what exactly happens if you try to useexecvp()withou...

Make is a UNIX tool and is used as a tool to simplify building executable from different modules of a project. There are various rules that are specified as target entries in the makefile. The make tool reads all these rules and behaves accordingly. ...

Consider this diagram to better understand the sequence of function calls that Python goes through when you call reduce() with an initializer: reduce(f, [1, 2, 3, 4, 5], 100) Again, reduce() isn’t the only way to make this calculation happen. You could also achieve the same resul...
