Type conversionFrijo Francis

Type conversion in C provides two methods: implicit type conversion which occurs automatically during expressions, and explicit type conversion using cast expressions. Implicit conversion occurs when different types are used in expressions, such as when an int is used in a calculation with a float. The usual arithmetic conversions implicitly promote operands to the smallest type that can accommodate both values. Explicit casting uses cast operators to force a type conversion.

Self assessmentarihantcollege9

Self-assessment allows students to reflect on their own work and performance, identify their strengths and weaknesses, and find ways to improve. It encourages students to take more responsibility for their learning, increases motivation and content retention, and promotes independent learning in a low-stress environment. For self-assessment to be effective, criteria must be clear and students need training, practice, and a trusting classroom environment.

Virtual Functions | Polymorphism | OOPshubham ghimire

Virtual functions allow derived classes to override base class functions. A virtual function is declared with the virtual keyword in the base class and redefined in derived classes. When called via a base class pointer, the correct overridden function in the derived class will be called based on the actual object type. Pure virtual functions are declared with =0 and force derived classes to provide an implementation. Virtual functions enable runtime polymorphism in C++.

Python: Basic InheritanceDamian T. Gordon

The document discusses basic inheritance in Python. It explains that all classes inherit from the base Object class. Inheritance allows creating subclasses that inherit attributes and methods from a parent superclass. This allows code reuse and adding specialized behavior. An example creates a Contact class to store names and emails, with a Supplier subclass that adds an "order" method. A SupplierCheck subclass then overrides the order method to check the customer balance before processing orders.

Activity based approach of learning mathematics-ThiyaguThiyagu K

A Mathematics Teacher has a variety of methods and techniques available for use in teaching mathematics. The selection of suitable method depends upon the objectives of the lesson, needs of the learner and the nature of the content. Some methods are more appropriate for individualised instruction. In Active learning methodologies, that shifts the focus of the classroom from teaching to learning to and from the teacher to the learner. Often, teaching and learning are linked logically in the teachers mind. The two processes are not linearly linked. Good teaching does not automatically lead to good learning. This is evidenced by the fact of un- interested, disengaged children in classrooms. The learner based curriculum places the child’s engagement with his/her learning at the centre and sees the teacher as a facilitator in the process. Activity based learning focuses use of these sense organs and learning should be based on doing some hands-on experiments and activities. The idea of activity-based learning is rooted in the common notion that children are active learners rather than passive recipients of information. If child is provided the opportunity to explore his/her own and provided an optimum learning environment then the learning becomes joyful and long-lasting. The key feature of the activity approach is that it uses child-friendly educational aids to foster self-learning and allows a child to study according to his/her aptitude and skill. At school level in mathematics the activity/activities may be in the form of game, puzzle, worksheet, paper folding/paper cutting, concept mapping of mathematical modelling etc.
