In a program we have any number of goto and label statements, the goto statement is followed by a label name, whenever goto statement is encountered, the control of the program jumps to the label specified in the goto statement. goto statements are almost never used in any development as th...
Thegotokeyword is part of the C language, and it provides a construct to do an unconditional jump.ifandswitchstatements are examples of conditional jumps.gotoconstruct consists of two parts:gotocall and label name. Any statement in code can be preceded by a label, which is just an identifier...
Working of goto in C++ Example: goto Statement // This program calculates the average of numbers entered by the user.// If the user enters a negative number, it ignores the number and// calculates the average number entered before it.#include<iostream>usingnamespacestd;intmain(){floatnum, ...

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:...
For more information about labels and the goto statement, see Labeled Statements and Using Labels with the goto Statement. Example In this example, a goto statement transfers control to the point labeled stop when i equals 3. 复制 // goto_statement.cpp #include <stdio.h> int main() { in...
..) { if(...) goto stop; . . . } } } stop: cout << "Error in program.\n"; Eliminating the goto would force a number of additional tests to be performed. A simple break statement would not work here, because it would only cause the program to exit from the innermost loop....
statement gotostatement From cppreference.com Transfers control unconditionally. Used when it is otherwise impossible to transfer control to the desired location using other statements. Syntax Explanation Thegotostatement transfers control to the location specified bylabel. Thegotostatement must be in the ...
