In C++ programming, the goto statement is used for altering the normal sequence of program execution by transferring control to some other part of the program. Syntax of goto Statement goto label; ... .. ... ...
In the following example, we search for the first appearance of the given string in the text, and once it is found, the loop is broken with the goto statement to move control at the end of the program. As a result, the cout statement indicating the failure message is skipped and only...
Thegotostatement transfers control to the location specified bylabel. Thegotostatement must be in the same function as thelabelit is referring, it may appear before or after the label. If transfer of control exits the scope of any automatic variables (e.g. by jumping backwards to a point be...

goto label; .. . label: statement;在这里,label 是识别被标记语句的标识符,可以是任何除 C++ 关键字以外的纯文本。标记语句可以是任何语句,放置在标识符和冒号(:)后边。流程图实例实例 #include <iostream> using namespace std; int main () { // 局部变量声明 int a = 10; // do 循环执行 LOOP:...
Jinku Hu2023年10月12日C++C++ Statement 本文將介紹如何在 C++ 中使用goto語句。 ADVERTISEMENT goto語句強制程式控制流跳轉到標籤指向的行。通常,C++ 中的任何語句都可以使用特殊符號進行標記,該符號由一個識別符號和一個冒號組成。通常,這些標籤識別符號在函式範圍內隨處可用。因此,它們可以通過位於標籤之前的goto語...
