Short notes on 1. Namespaces 2. Exception handling 3. Basic functions of seekg(), seekp(), tellg(), tellp()
1. Namespaces: Namespaces are a feature in C++ that allow us to group related functions, classes, and variables under a single name. This helps in preventing naming conflicts and organizing code. We can create a namespace using the keyword "namespace" followed by the namespace name and enclosing the contents within curly braces. We can access the contents of a namespace using the scope resolution operator "::". For example: namespace myNamespace { int myFunction() { // function code } } int main() { myNamespace::myFunction(); // accessing function from the namespace return 0; } 2. Exception handling: Exception handling is a mechanism in C++ that allows us to handle errors and unexpected events that occur during program execution. We can use the keywords "try", "catch" and "throw" to implement exception handling. We enclose the code that can generate an exception within the try block. If an exception is thrown, the ...
