What are the conditional statement of turbo c plus plus dos based?
Statements that check an expression then may or may not execute a statement or group of statements depending on the result of the condition.
What optional statement can be used in a case structure to execute statements when all other conditions are false?
default : <statement>; i.e. switch (value) { case 1 : do_this(); break; case 2 : do_that(); break; default : do_whatever(); }
What structure can be execute a set of statements only under certain circumstances?
Decision structure.
In which of the following scenarios would you need to use a nested IF statement?
You use a nested if when the condition is dependent upon another condition. For example: if (ptr != nullptr) { // ptr is non-null -- test the value it refers to if (ptr* == 0) { // the value pointed to by ptr is zero } else { // the value pointed to by ptr is non-zero } } In this case, the alternative to a nested if creates an inefficiency: if (ptr != nullptr && *ptr == 0 ) { // ptr is valid and refers to the value zero } else if (ptr != nullptr) { // ptr is valid and refers to a non-zero value } In this example, the expression "ptr != nullptr" is evaluated twice when ptr is valid and refers to a non-zero value. The nested if only evaluates this expression one time.
Why for loop is not terminated in c?
Of course the for loop is terminated in C. All statements are terminated. Look at the syntax of the for statement... for (init-statement; test-condition; loop-statement) body-statement; That looks quite terminated to me. (By the semi-colon) Perhaps you are thinking about statement blocks... for (init-statement; test-condition; loop-statement) { statement; statement; ... statement; } ... Well, that is just fine because the body-statement, like any other statement, can be replaced by one or more statements enclosed in braces. There is still a terminating semi-colon on each statement. if i am understanding ur ques. right then according to me it is correct that for loop is not terminated because we do not execute for loop.we only check the conditions. those statements are terminated which we want to execute. because using a semicolon or terminating the statement means that statement is execitable.

How do you group multiple PHP statements under an if statement?
If I got your question correctly, you want multiple statements to be executed using if-else statement. Here goes the code for it if($x>0) { // multiple statments here // As long as statements are in curly bracket // All of them would execute // before the if statement finishes } else { // same way put all your multiple statements // in curly brackets. All of them would execute // using a single if-else statement }

How If and else run at a time?
The standard syntax is:if( conditional_expression )statement;[[else if( conditional_expression )statement;[else if...]]else statement;][] denotes optional components. Each statement may be a single statement, or may be multiple statements surrounded by braces {}.The if( conditional expression ) statement; is the only required component. In plain English, this reads: if the conditional expression is true, then execute the following statement, otherwise skip to the line following the statement.If the next line is an else statement, then the line reads: if the conditional expression is true, then execute the statement and skip over the else statement. But if the conditional expression is false, then skip over the statement and execute the else statement instead.if( conditional_expression )statement; // execute when conditional expression is trueelsestatement; // execute when conditional expression is falseThe statement following the else can be another ifstatement (a nested if):if( conditional_expression_1 )statement; // execute when conditional_expression_1 is true.else if( conditional_expression_2)statement; // execute when conditional_expression_1 is false and _2 is true.elsestatement; // execute when both _1 and _2 are both false.Note that if an else statement is used without a following if statement, it must appear after all other else if statements.

What is difference between IF THEN and IF THEN ELSE statement?
An if-then statement, or simply an if statement, checks if a stated condition is true. If the condition is true, then a block of code will then execute. Example: if number equals 3 print out "Number equals 3" An if-then-else statement, or simply an if-else statement, checks if a stated condition is true. If the condition is true, then a certain block of code will then execute. If the condition is false, then a different block of code will then execute. Example: if number equals 3 print out "Number equals 3" else print out "Number does not equal 3" For both if statements and if-else statements, there is only one stated condition. The difference between them is that an if statement will only cause something to happen if the condition is true. An if-else statement will execute a block of code whether the condition is true or false.
What is the difference between do while and while?
In while, from the very first term, every time, the related conditions in while will be checked and then the statements will execute. But, in do-while, all the statements under do will execute once and then compiler will check the while condition. Therefore, only first time only statements will execute without checking the conditions in while, but not from the second term repetition. written by DILSHAN MADUSANKA dilshanmadusanka@yahoo.com
Looping statement in c plus plus?
There are several 'looping' statements in C++. They are:while () { }do { } while () ;for (index-start, index-end; index increment/decrement) { }They are used to repetitively execute statements as long as the statement(s) controlling the loop are true.

What are conditional statements?
Conditional statements are used in programming to make decisions based on certain conditions. They allow the program to execute different code blocks depending on whether a condition is true or false. Common conditional statements include if, else, and else if.
