Advantage and Disadvantage of pointer in c

Advantage and Disadvantage of the pointer in c

Advantage: 

• Pointers provide direct access to memory
• Pointers provide a way to return more than one value to the functions
• Reduces the storage space and complexity of the program
• Addresses of objects can be extracted using pointers
• Pointers allow us to resize the dynamically allocated memory block.
•  Pointers help us to build complex data structures like linked list, stack, queues, trees, graphs etc.
• Pointers allow us to perform dynamic memory allocation and deallocation.
• Pointers can be used to pass information back and forth between the calling function and called the function.
• Provides an alternate way to access array elements
• Reduces the execution time of the program

Disadvantage: 

• Pointers are slower than normal variables.
• Uninitialized pointers might cause the segmentation fault.
• If pointers values updated with a wrong value, it might lead to memory corruption.
• Crashes are common occurance in pointers.
• Pointers syntax is really complicated.
• Programming using pointers is really hard.
• It is really hard to debug a program which one is create using pointers.
