// statement(s) will execute if the Boolean expression is false } 流程图(Flowchart) if块保护条件表达式。 如果布尔表达式的计算结果为true,则执行与if语句关联的块。 if块后面可以跟一个可选的else语句。 如果表达式的计算结果为false,则执行与else块关联的指令块。 例子(Example) var num = 12; if (nu...
Python implementation of the above flowchart is as follows − ifexpr==True:stmt1 stmt2 stmt3else:stmt4 stmt5 stmt6 Stmt7 Python if-else Statement Example Let us understand the use ofif-elsestatements with the following example. Here, variableagecan take different values. If the expressionag...
Understand Python if-else statements easily with this comprehensive guide. Discover how to use conditional logic to control the flow of your programs.
The examples of IF/THEN/ELSE instructions in previouschapters demonstrated the two-choice selection. In a flow chart, this appears as follows: As a REXX instruction, the flowchart example looks like: IF expression THEN instruction ELSE instruction You can also arrange the clauses in one of the ...
If the input age is 18 or greater than 18 then the voter is eligible to vote, else not. import java.util.Scanner; public class example { public static void main(String[] args) { int voter_age; System.out.println("Enter the age: "); ...
In instances where the condition yields a false outcome, the code segment enfolded within the secondary set of curly braces (the “else” block) becomes active and is executed. Flowchart of if-else Statement in C: The flowchart of the “if-else” statement helps illustrate its working +--...
Let’s see the flowchart of if-else If you observe the above flow chart, first the controller will come to if condition and evaluate the condition if it is true and then the statements of if block will be executed otherwise “else” block will be executed and later the rest of the code...
log("Even"); } else { console.log("Odd"); } The above example prints whether the value in a variable is even or odd. The if block checks the divisibility of the value by 2 to determine the same. Here is the output of the above code −...
}else{ // Executed if the condition is false } The syntax is the same as the one given at the beginning of the article. How Does If-Else In C++ Work? The working mechanism of the if-else condition in C++ can be seen in the flowchart shared at the beginning of the article. In the...
The control flow of the program would be as given in the flowchart below: The flowchart of the if…else condition The syntax of theif…elsecondition is: if (1stcondition==True) { // block of code to be executed } else if (2ndcondition==False) ...
