在编写程序时,可能需要从一组给定路径中采用一个。在这种情况下,您需要使用条件语句,以使程序能够做出正确的决定并执行正确的操作。

Solidity支持条件语句,这些条件语句用于根据不同的条件执行不同的操作。在这里,我们将解释if..else语句。

if-else的流程图

以下流程图显示了if-else语句的工作方式。

做决定

Solidity支持以下形式的if..else语句-

Sr.No Statements & Description
1 if statement

The if statement is the fundamental control statement that allows Solidity to make decisions and execute statements conditionally.

2 if…else statement

The ‘if…else’ statement is the next form of control statement that allows Solidity to execute statements in a more controlled way.

3 if…else if… statement.

The if…else if… statement is an advanced form of if…else that allows Solidity to make a correct decision out of several conditions.
