Statements that check an expression then may or may not execute a statement or group of statements depending on the result of the condition.

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.
They are called statements. They have no other special name. A group of statements are called "Block statements".

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 }

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
