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.
What is nesting in C programming?
Nesting can be a very handy tool in C++, but should be avoided if possible.C++ gives us If statements, For loops and many other things. These can be nested. For example:A nested If statement://outer if statementIf( this is true ){//nested if statementif( this is also true ){//do something}else{//do something else}}
What is property procedure?
A property procedure is a series of Visual Basic statements that manipulate a custom property on a module, class, or structure. Property procedures are also known as property accessors.
Difference between amplifier and feedback amplifier?
An ordinary amplifier can have high gain but is unstable, drifts, can oscillate, etc. An amplifier with negative feedback has lower gain but is stable, does not drift, won't oscillate, etc.
What is meant by the phrase one block of code can be nested in another?
It simply means one code block contains another code block. How you achieve this depends on the language, but in many languages we use opening and closing braces to define a code block. function foo () { // start of function block { // start of nested block // ... } // end of nested block } // end of function block Nested code blocks are typically used to define a new scope within an existing scope. Any variables declared within the nested block are local to the scope of that block and will fall from scope when we exit the nested block. This can be useful when we want to instantiate new variables within a larger scope but want to localise them to the code block that actually uses them. In some languages (such as C++) this also allows us to redefine names that were initially defined by the enclosing scope, temporarily hiding the original names from within the nested scope (only the local names are visible). When we exit the nested block, the original names become visible again. However, referring to two separate variables by the same name within two scopes of the same function can make code difficult to read, so this is best avoided.

Can you have nested namespace?
Of course! All namespaces are nested by default since all namespaces exist in the global namespace. A class is also a namespace; therefore classes can also be nested.
What does an IF Statement do?
An if statement is a control statement. It is used to control whether a statement executes or not, depending on whether a control expression evaluates true or false.if (expression) {statement;}In the above example, the expression is evaluated. If true, the statement executes, otherwise it does not.if (expression) {statement1;} else {statement2;}In the above example, the expression is evaluated. If true, statement1 executes otherwise statement2 executes.Note that if statements may be chained together using else if statements. The final else clause (if present) then becomes the default case. Also, any statement within an if statement may itself be an if statement, known as a nested if. If statements may be chained or nested to any depth.
A trite statement is called a what?
A trite statement is called a bromide. Bromide is defined as a phrase that has been used excessively and is insincere and not original. Trite statements are also called cliches.
What is property procedure?
A property procedure is a series of Visual Basic statements that manipulate a custom property on a module, class, or structure. Property procedures are also known as property accessors.
Where can one find more information about laser whitening of teeth?
The Food and Drug Administration has produced a series of reports on the use of radiation-emitting products on teeth. The American Dental Association has also produced a series of FAQs and issued statements regarding the practice.
Is there a series after the Percy Jackson series?
Yes. It is called the Heroes of Olympus. The first one is called The Lost Hero, and the was published recently (10-4-2011) and is called The Son of Neptune. Rick Riordan has also written another series called The Kane Chronicles, a total different series about Egyptian Mythology. Even more recently published is the Son of Sobek and it's series.
What is nested macro calls?
Nested macro calls refer to the macro calls within the macros. A macros is available within other macro definitions also. In the scenario when a macro call occurs, which contains another macro call, the macro processor generates the nested macro definition as text and places it on the input stack. The definition of the macro is then scanned and the macro processor complies it.
