How To Implement Goto Statement In C++?

No matter what the programming language, programmers  have hard time when it comes to traversing between the code. In this article we would be exploring ‘Goto Statement In C++’ that helps us simplify the process of traversing along the code.

Following are pointers to be discussed in this article,

So let us start with article by understanding the first topic,

What is Goto Statement in C++?

The goto statement in C++ is an unconditional jump statement used for transferring the control of a program. It allows the program’s execution flow to jump to a specified location within the function. There are two ways to call the goto statement.

Syntax 1Syntax 2

goto label;

//block of statements

label:  ;

label:  ;

//block of statements

goto  label;

A label’s name is a user defined identifier and is distinguished by the colon that immediately follows its name. The statement immediately followed after “label:” is the statement to be executed after goto statement. The goto statement jump to the statement marked with a label.

Examples Of Goto Statement

Let’s see few examples on how to use goto statement in C++

Example 1:

//based on syntax 1
using namespace std;
// function to check greater number
void checkGreater()
int i, j;
goto iGreater;
goto jGreater;
cout<<i<<" is greater";
cout<<j<<" is greater";
// main method to test above function
int main()
return 0;

The return statement after “iGreater:” in “checkGreater” function. Once the control jumps to the label with “iGreater:”, the program will execute every piece of code after it. So it is important to return if the number is greater. Otherwise the code after label “jGreater:” will also gets executed as it comes after “iGreater:”.

Example 2:

//based on Syntax 2
#include <iostream> 
using namespace std; 
// function to print numbers from 1 to 5
void printNumbers() 
int n = 1; 
cout << n << " "; 
if (n <= 5) 
goto print; 
// main method to test above function 
int main() 
return 0; 


output - Goto Statement in C++ - Edureka

In the above program, the label is named as “print” and the goto statement jumps to the “print” label only when the variable “n” is less than or equal to 5.

Why not to use Goto Statement?

Early programming languages like FORTRAN and early versions of BASIC did not have structured statements like while, so programmers were forced to use goto statements to write loops. The problem with using goto statements is that it is easy to develop program logic that is very difficult to understand, even for the original author of the code.

It is easy to get caught in an infinite loop if the goto point is above the goto call.

How to avoid goto statement?

Goto isn’t inevitable and can be avoided. Goto statement can be avoided using break and continue statements.
