Want this question answered?
The scanf() function in the <stdio.h> C standard library header.
size of the data type being read
They tell the CPU where to find the data, when to read it, and what to do with it.
The function header. The return value is written before the name of the function. This return type must match the type of the value returned in a return statement.
Passing a single value to a function is often just a simple integer. But passing an array, character string or other data structure is typically "pass by reference", or in other words, the calling statement will 'point to' the place in memory where the data structure resides.When a function is called using a pointer to a data structure, both the calling environment and the called function are referencing the same data; any changes made to the data in the structure by the function will have changed the data that the original calling environment sees.However, when a value is passed to a function, the function creates it's own copy of the value, and can change it in any way without changing the original value.
It means 'no more data to read in this file'.

A function statement is a block where the function is declared and defined.

The Functions of the instruction set is to instruct All CPU's with a set of instructions: Tells the CPU where to find data When to read the data What to do with the data. Hope that helps Don
IF function
IF, in C and C++, is not a function - it is a statement. There are two parameters... if (expression) statement; The expression is evaluated. If it has logical result true, or arithmentic result not zero, the statement is executed; if not, the statement is not executed. The statement can be a single statement, in which it is terminated with a semi-colon, or it can be a block of statements, in which it is surrounded by braces.
Statements are composed from expressions. A semi-colon turns an expression into a statement. A function is not a statement it is a type definition. A statement block is a compound statement, one or more statements delimited by braces, {}. A function block is the body of a function. The body must be enclosed in braces, {}.
