5 types of Operators

is an syntactically correct combinations of operands and operators.

They both have a TYPE and VALUE

Two basic types of arithmetic operators:

An operator that only requires one operand

An operator that requires two operands

There are only _____ arithmetic operator, and ______ arithmetic operators.

Rules which determine precisely how expressions are evaluated

Terms which are always evaluated first

In ______ , all decimal portions of numbers are lost (or truncated).

Evaluates an arithmetic expression consisting of an operator and two integer operands.

Characterized by : variable = expression

Basic operator in C

Can be used more than once in an expression

An assumption on which tests the validity or effect of something else

Are used to represent true or false because there is no actual boolean or logical data type in C

An expression that is either true (represented by 1) or false (represented by 0)

Are used to test specific conditions and requires the use of two operands

Relational Operators == and != are often referred to as-

Connects two or more relational expressions into one or reverse the logic of an expression.

represents a non-zero value (can be negative or positive numbers, float, character, string)

represents a zero value (integer or float value)

symbol used as an increment operator to increment or add 1 to the operand value

value is first incremented and then used inside the expression

value is first used in an expression and then incremented

increment and decrement operators are considered as _____ since they require only one operand

symbol used as an decrement operator to decrement or subtract 1 to the operand value

value is first decremented and then used inside the expression

value if first used in an expression and then decremented

operators used in special situations

5 types of special operator

returns the address of the variable

symbol used as a reference operator

returns the value of a variable pointed by the specified pointer

symbol used as a dereference operator

used to determine or compute the operand's size in bytes

the size of int data type in the TurboC application, as it is a 16-bit-based application

the size of int data type in today's compilers (e.g., MinGW GCC Compiler)

size of char data type

size of float data type

size of double data type

helps on creating a short way of writing conditional statements

syntax of ternary operator

comma can be used as a ____ or as a ____

has the least precedence of all C operators

returns the rightmost value of an expression but first evaluate the rest of the expressions and discard their values

way of converting one datatype to another

automatically done by the compiler

in the implicit type conversion, datatypes in the expression will be converted into the ________ datatype used within the expression

basic datatype upgrade sequence (least to greatest)

specifies on which datatype to be converted

explicit type conversion is also called as _______

There are three (3) basic classifications of statements in C, and actually, there are very few statements of each type.

(3) basic classifications of statements in C,

3 type of Primitive statements

• is made up of a null expression followed by a semicolon.

• a null expression is an empty expression

( ; )

• Expression and function call statements expression; function_call();

• or also called as block is formed by placing more than one statement inside curly braces ({}). { statement; statement; }

Conditional branches - make decision before branching: and its 2 type

Single-decision branch - ____

Multi-decision branch

Decision statements are actually part of a larger category statements known as ??

2 kinds of branch statements?

involves making one or more decisions before branching, and are thus referred to as single-decision or multi-decision branches.

direct branches which involve no decision. The goto statement is an example of an unconditional branch.

The___ statement is a conditional, single-decision branch.

The if statement has the general format of ?

IF STATEMENTS may be a ____ statement or ___ statement.

it allows you to check between multiple test expressions and execute different statements.

a conditional, multi-decision branch. The previous example of successive comparison of equality or value of the operand is so common in programming, a special construct exist in C to handle such comparison.

____ is evaluated and its value is compared.

The expression and the constant compared against must be an _____ constants or expressions. They may NOT contain variables.

The default case is optional, but if it exists there can be ____. It may occur anywhere in the list of case clauses but usually occur at the end

One of the fundamental properties of a computer is its ability to repetitively execute a set of statements.

These looping capabilities enable the programmer to develop concise programs containing repetitive processes that could otherwise require thousands of program statements to perform.

C contains three looping constructs:

The _____ statements may be described as test-before-execute. If the controlling condition results initially to a zero or false value, the body of the loop is never executed.

The ____statement on the other hand may be considered as execute-before-test. The body of the loop is always executed at least once.

The _____is used to execute a statement as long as a condition remains true.

with a syntax of

While (expression){ //statement }

The conditional expression, of course, may be a _____ or ____.

_____ is usually used when the number of times the loop must be executed is not known in advance.

The ____ is generally used for counted loops.

The ______ will execute a statement and then evaluate a conditional expression.

The statements____ and ___ are used to interrupt the normal flow of loops and the switch statement.

The ____ is similar to the break statement, except it does not cause the loop to terminate. Rather it causes the loop to be continued.

The ____ causes the flow of the program to branch to the statement immediately following the appropriate label.

A _____is a name that is formed with the same rules in identifiers and must be immediately followed by a colon.

The _____ interrupts the normal sequential flow of a program, without involving a decision.

Since goto statement is an example of _____ it is difficult to use without the help of conditional branch statements.

We can properly use goto statements by using some of the _____to avoid infinite looping execution.
