C++ goto statement

goto statement is used for unconditional transfer of control anywhere in program. It is normally used with selection structure ( if statement ). goto statement is always used with predefined label. Label is the point where goto statement transfer control.

Syntax

label :

   goto label;

Label may be any valid identifier name such as name of variable. colon is used after label.

Example

#include <iostream>
using namespace std;

int main(int argc, char** argv) {
	
	int a = 1;
	
	doAgain: // This is label.
		if( a<=5 ) {
			cout<<a<<"\n";
			a = a + 1;
			goto doAgain; // here is goto statement is used.
		}
	
	return 0;
}

The above code example will print counting from 1 to 10. Hence it does not use any iterative structure such as while, do while or for loop. But with the help of goto statement we can repeat the same task.
