Apr 01, 2008 Using goto statements is usually proclaimed a terrible idea by programmers, teachers, etc. And usually it is. I haven't come across a problem yet in C or C (or any other high-level language) that NEEDED goto statements - it's always been a loop, or a function, or something like that.
error message is seen on the goto statement. did I miss library ?
this is a part of script.
Evil GoTo Home. Programming Forum. Except for the two small sections that explain what goto and label are, and the uses of goto to explain what under flow control constructs do, all the mentions of goto relate to the types of ill-formed code they can cause. Program Problem in VS C 6.0 from Dev C; enigma machine going back to main. A goto statement in C programming provides an unconditional jump from the 'goto' to a labeled statement in the same function. NOTE − Use of goto statement is highly discouraged in any programming language because it makes difficult to trace the control flow of a program, making the program hard to understand and hard to modify.
#include <cstdlib>
#include <iostream>
#include <conio.h>
using namespace std;
int main() {
int a = 0, b = 0, c = 0;
cin >> a >> b >> c; //assume error checking etc
start:
if(a > 6) goto a;
else if(b < 2) goto b;
goto 5;

goto start;

Why are you using goto. It is not a good programming practice to use goto.
You are also not using the proper 'goto label'. Like
and you are not declaring any label with identifier 'a'.

A goto statement provides an unconditional jump from the goto to a labeled statement in the same function.
NOTE − Use of goto statement is highly discouraged because it makes difficult to trace the control flow of a program, making the program hard to understand and hard to modify. Any program that uses a goto can be rewritten so that it doesn't need the goto.
Syntax
The syntax of a goto statement in C++ is −
Where label is an identifier that identifies a labeled statement. A labeled statement is any statement that is preceded by an identifier followed by a colon (:).

Example
When the above code is compiled and executed, it produces the following result −
One good use of goto is to exit from a deeply nested routine. For example, consider the following code fragment −
Sas Goto Label
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.
