Lots of “modern” languages, like Rust, have converted statement syntax-forms into expressions. For example, if/else, which in C is a statement form, is in Rust a ternary expression. For another example, a series of expressions separated by semicolons becomes another expression, where in C...
An if else statement in programming is a conditional statement that runs a different set of statements depending on whether an expression is true or false. A typical if else statement would appear similar to the one below (this example is JavaScript, and would be similar in other C-style ...

Continue: When the ‘continue’ statement is encountered in a loop, it skips the current iteration of the loop and moves on to the next iteration. It makes the loop jump directly to its condition check or increment/decrement expression by skipping the remaining code of that iteration. If you...
Below is an example of an if, elsif, and else conditional statement in Perl.#!/usr/bin/perl print "Enter number: "; my $number = <STDIN>; if ($number <= 10) { print "Your number is less than or equal to 10"; } elsif ($number <= 50) { print "Your number is more than ...

skipped, and the program moves on to the next statement after the if block. In some cases, you may want to specify an alternative action using an else statement. The else statement is used after an if statement to define a block of code that should be executed if the condition is false...
