If the condition in the if statement is true, the code block inside the curly brackets is executed. In case the condition evaluates to false, we move to the line of code after the if-block. If there are no curly
名字绑定的作用域是一个块,这样的作用域就是块作用域。它几乎存在于所有的块结构化编程语言中,例如 C 系语言。大多数情况下块一般都在函数内。 块作用域一般用于控制流,比如 if,while 和 for 循环。但是拥有块作用域的语言一般都会允许使用“裸露”的块,这样就可以在块中定义辅助变量并使用,在块终结时销毁。
When the condition enclosed within the parentheses is assessed as true, the code snippet confined within the initial set of curly braces (the “if” block) is triggered for execution. In instances where the condition yields a false outcome, the code segment enfolded within the secondary set of...
As mentioned before, there are generally three types of loops used in C++: For loop: It allows users to execute a block of code a specific number of times. While loop: It allows users to execute a block of code if a specific condition is true. Do-while loop: This allows users to ex...
Example for C If-Else Statement In the following example, we have an if-else with condition to check whether the number is even. If the number is even, then we shall print a message to the console that the number is even. This is if block, and have just a single statement. If the...

To perform complex queries and evaluate multiple conditions, IF statements can be nested. The following is the syntax for a nested IF statement:IF [condition1] THEN IF [condition2] THEN [value1] ELSE [value2] END ELSE [value3] END
