In C++ , goto statement is used for change the normal sequence of program execution by transferring control to other a part of the program.
The C++ goto statement is additionally referred to as jump statement.

Example : -
#include
<iostream>
using namespace std;
int main() {
using namespace std;
int main() {
int i = 10;
int j = 20;
if(i > j)
{
else
{
igreater:
}
int j = 20;
if(i > j)
{
goto igreater;
}else
{
goto jgreater;
}igreater:
cout << i <<" is greater";
return;
jgreater:return;
cout << j <<" is greater";
return;
return;
Output:
20 is greater
20 is greater
Note:
Use of goto statement is very discouraged because it makes difficult to trace the control flow of a program, making the program hard to know and hard to switch .
Any program that uses a goto are often rewritten in order that it doesn't need the goto.

The goto statement gives power to leap to any a part of program but, makes the logic of the program complex.
In modern programming, goto statement is taken into account a harmful and a nasty programming practice.
