In computer science, a smart pointer is an abstract data type that simulates a pointer while providing additional features, such as automatic garbage collection or bounds checking. These additional features are intended to reduce bugs caused by the misuse of pointers while retaining efficiency. Smart pointers typically keep track of the objects they point to for the purpose of memory management. read less

Inline function instruct compiler to insert complete body of the function wherever that function got used in code. Compiler takes decision. Pointers are used.

C++ supports pointers. An inline function is function whose complied code is inline with the rest of the program. Inline function run faster than regular functions.

Function which replace in the position where it is called is inline function. Their work is similar to macros. We can use Pointers in C++.

read more C++ inline function is powerful concept that is commonly used with classes. If a function is inline, the compiler places a copy of the code of that function at each point where the function is called at compile time.

These additional features are intended to reduce bugs caused by the misuse of pointers while retaining efficiency. Smart pointers typically keep track of the objects they point to for the purpose of memory management. The misuse of pointers is a major source of bugs: the constant allocation, deallocation and referencing that must be performed by a program written using pointers introduces the risk that memory leaks will occur. Smart pointers try to prevent memory leaks by making the resource deallocation automatic: when the pointer (or the last in a series of pointers) to an object is destroyed, for example because it goes out of scope, the pointed object is destroyed too. read less

read more In a program, If you write a small function which you feel is called again and again, then to reduce the function calls declare that function as inline. By doing we, we request the compiler that "if possible replace the function call with the actual function". Pointers are not used in C++ because we have got a good replacement called as "reference" , which does the same work as that of pointers but in a safe way and less cumbersome code. You need not use the (*) deference symbol everywhere. These are explanation in layman terms. For more details you can refer standard books. read less

Whenever you call an inline function, the compiler will replace the function call with the function body.

Inline functions are lot like macros. They're are replaced by compiler with the implementation.

read more Inline functions are a lot like a placeholder. Once you define an inline function, using the 'inline' keyword, whenever you call that function the compiler will replace the function call with the actual code from the function. In C++ the emphasis would be on garbage collection and preventing memory leaks (just to name two). Pointers are a fundamental part of the language, so not using them is pretty much impossible except in the most trival of programs. read less

What is the actual size of INT in the C language, 2 or 4 bytes? 
The actual size to int is determined by the compiler as the program runs. But theoretically the size is 2 bytes. You can increase the size by adding keyword long infront of it to make the size 4 bytes. Eg int a; // 2 bytes Long int b; // 4 bytes
