Functions are used to reduce the lines of code and the complexity of the code. For an instance let us suppose that you want to calculate the factorial of numbers at different times in a program. There are two ways to do this
1. Write a 4-5 line code every time you want to calculate factorial.
2. Write a function of 4-5 lines which calculates the factorial and call that function every time you need to calculate factorial by just writing a single line.
In C++ you can pass the variable, address of the variable or a reference to the variable in a function

The normal way a function works is that whenever your code encounters a call to the function, it jumps to the body of the function code. An inline function tells the compiler that it should actually copy over the code from a function body into all places where that function is called. In some cases this can cause a dramatic reduction in run time, but in others it causes nothing more than increasing the size of the produced executable. Function overloading refers to the ability to have multiple functions with the same name, but different parameter types.
Outline is the opposite of inline. An inline expanded function is any function or class method where the declaration also provides the definition (the implementation). This is known as implicit inline expansion. Where the definition is kept separate from the declaration, you may use the inline keyword to specifiy that the function should be inline. This is known as explicit inline expansion. Inline expanded functions (whether implied or explicit) does NOT mean the function will in fact be inline expanded. It is merely a suggestion to the compiler. If the compiler's optimisers determine that there is no advantage to be gained by inline expanding a particular function, then that function becomes an outline function. Inline expansion simply means that the body of the function is inserted in place of the function call. Function calls are expensive in terms of memory and performance, so by eliminating the function call completely, your code performs faster and uses less memory. However, functions that are called many times throughout your code will result in a much larger code size, and large code runs slower than small code. Thus the benefit of eliminating a function call has to be weighed against the increased code size. Although some compilers do allow you to override the compiler's inline expansion optimisers, this is strictly non-standard. The best judge of what to expand and what not to expand is best left in the hands of the compiler, and indiscriminate use of the inline keyword should generally be avoided.
A function prototype is basically a definition for a function. It is structured in the same way that a normal function is structured, except instead of containing code, the prototype ends in a semicolon.Normally, the C compiler will make a single pass over each file you compile. If it encounters a call to a function that it has not yet been defined, the compiler has no idea what to do and throws an error. This can be solved in one of two ways.The first is to restructure your program so that all functions appear only before they are called in another function.The second solution is to write a function prototype at the beginning of the file. This will ensure that the C compiler reads and processes the function definition before there's a chance that the function will be called.For example, let's take a look at a few functions form a linked list implementation.// Sample structuresstruct linked_list_node {int data;struct linked_list_node *next;};struct linked_list {int size;struct linked_list_node *root;};// Function Prototypesvoid deleteLinkedList(struct linked_list *list);void deleteNodes(struct linked_list_node *node);// Actual functions:// deletes the given linked listvoid deleteLinkedList(struct linked_list *list) {if( list != NULL ) {// delete nodesdeleteNodes(list->root);// lose the pointerlist->root = NULL;// delete actual listfree(list);}}// deletes all nodes starting at nodevoid deleteNodes(struct linked_list_node *node) {if( node != NULL ) {// deallocate next, if it existsif( node->next != NULL ) {deleteNodes(node->next);// lose the pointernode->next = NULL;}// deallocate nodefree(node);}}
Poor countries can benefit from a limited amount of scientific technology. They do not have the resources to utilize higher levels of technology, but they can benefit from things that improve the quality of food production, health care, and sanitation.
Marginal benefit 'occurs' for any benefit (price) function, since a marginal term is simply the first-order derivative of its parent function. Marginal benefit is strictly greater than zero only when a benefit function is always increasing in total benefit over its domain.
A situation that would benefit from a written argument is when presenting a case in a court of law, where a well-structured and persuasive written argument can help support legal reasoning and advocate for a particular outcome effectively. The clarity and organization of a written argument can also be beneficial in academic settings, such as when writing research papers or essays to defend a thesis or hypothesis.
