Pointers: Applications and Memory Management

This lecture covers various applications of pointers in organizing data structures like trees and graphs, as well as dynamic memory allocation. It also explores the use of pointers in accessing fields of a structure, the precedence of pointer operators, and the different ways of using 'const' with pointers. The lecture delves into the complexities of handling complex data structures like trees and graphs using pointers, emphasizing the challenges and solutions. It also discusses the truth about the 'main()' function in C, the memory organization in program execution, and the importance of dynamic memory allocation. The lecture concludes with the risks associated with manual memory management and the benefits of using vectors as an alternative.
