If-Else Statement in C - Learn how to use if-else statements in C programming with examples and detailed explanations. Master conditional logic for effective coding.
Boolean operators allow you to create more complex conditional statements. For example, if you wish to check if a variable is both greater than five and less than ten, you could use the Boolean AND to ensure both var > 5 and var < 10 are true. In the following discussion of Boolean op...
There are several sections of the bash man page that provide further detail on the topicscovered in this chapter: bash 手册页中有几部分对本章中涵盖的主题提供了更详细的内容: Lists ( 讨论控制操作符 || 和&& ) Compound Commands ( 讨论 [[ ]], (( )) 和if ) CONDITIONAL EXPRESSIONS (条件...

if conditional_test: do something 在第1行中,可以包含任何条件测试,而在紧跟在测试后面的缩进代码块中,可执行任何操作,如果条件测试的结果为True,Python就会执行紧跟在if语句后面的代码;否则Python将忽略这些代码。 假设有一个表示某人的年龄的变量,而我们想知道这个人是否够投票的年龄,可使用如下代码将其实现: age...
