To debug a particular program without affecting others, use breakpoints and step through the code.

• Set a breakpoint in the program you want to debug

• Step through the code using a debugger to identify the issue

• Use logging statements to track the flow of the program

• Use conditional breakpoints to stop the program at specific points

OOPs concepts are the fundamental principles of object-oriented programming.

• Encapsulation - binding data and functions that manipulate the data

• Inheritance - creating new classes from existing ones

• Polymorphism - ability of objects to take on many forms

Storage classes in C define the scope and lifetime of variables.

• There are four storage classes in C: auto, register, static, and extern.

• Auto variables are local to a block and have automatic storage duration.

• Register variables are stored in CPU registers for faster access.

• Static variables have a lifetime throughout the program and are initialized only once.

• Extern variables are declared outside any function and can be a...read more

Linked list is a linear data structure. DFS and BFS are graph traversal algorithms.

• Linked list is a collection of nodes where each node points to the next node.

• DFS (Depth First Search) is a traversal algorithm that explores as far as possible along each branch before backtracking.

• BFS (Breadth First Search) is a traversal algorithm that explores all the vertices of a graph in breadth-first order.

• Example of linked list: ...read more
