Typically, when using a switch statement, if a case meets the condition, the code block of that case will automatically exit the switch statement and will not continue to execute the subsequent cases. However, using the &#8220;fallthrough&#8221; keyword can override this default behavior, allowing for the code block of the next case to be executed after the condition of the current case is met.<\/p>\n<p>Here is an example of using the &#8220;fallthrough&#8221; keyword:<\/p>\n<pre class=\"post-pre\"><code><span class=\"hljs-keyword\">package<\/span> main\r\n\r\n<span class=\"hljs-keyword\">import<\/span> <span class=\"hljs-string\">\"fmt\"<\/span>\r\n\r\n<span class=\"hljs-function\"><span class=\"hljs-keyword\">func<\/span> <span class=\"hljs-title\">main<\/span><span class=\"hljs-params\">()<\/span><\/span> {\r\n    num := <span class=\"hljs-number\">2<\/span>\r\n    <span class=\"hljs-keyword\">switch<\/span> num {\r\n    <span class=\"hljs-keyword\">case<\/span> <span class=\"hljs-number\">1<\/span>:\r\n        fmt.Println(<span class=\"hljs-string\">\"Num is 1\"<\/span>)\r\n        <span class=\"hljs-keyword\">fallthrough<\/span>\r\n    <span class=\"hljs-keyword\">case<\/span> <span class=\"hljs-number\">2<\/span>:\r\n        fmt.Println(<span class=\"hljs-string\">\"Num is 2\"<\/span>)\r\n        <span class=\"hljs-keyword\">fallthrough<\/span>\r\n    <span class=\"hljs-keyword\">case<\/span> <span class=\"hljs-number\">3<\/span>:\r\n        fmt.Println(<span class=\"hljs-string\">\"Num is 3\"<\/span>)\r\n    }\r\n}\r\n<\/code><\/pre>\n<p>In the example above, when the value of num is 2, after executing the code block of case 2, the fallthrough keyword is used, which will continue to execute the code block of the next case.
