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, {}.
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.
It is a function.
statement should not return a value but function returns a value
...a function call.

It is a function.
Any experssion including assignment or a function call can be a statement in C
statement should not return a value but function returns a value
a = b = c
...a function call.
It is a statement; you can create a loop with it: while (<condition>) <statement>
A compound statement consists of none or more C++ statements enclosed within a set of braces: {}. It is an essential concept in C++ and is central to the idea of nesting constructs. For example, the if statement has the form:-if ( expression ) statementwhich would severely limit its use were it not for the fact that a compound statement is itself a statement. Consequently any number of statements can be enclosed within a set of braces, including other if and compound ones, and the resulting compound statement used with the if statement. For example:-
It's a function, not a statement. Use your help system to find out its purpose.
return 0
Yes, you can call a function from within a switch statement in C. switch (i) { case 0: function1(i); break; case 1: function2(i); break; default: function3(i); break; } When the function returns, you will still be in the switch statement.
