Jump Statements

Jump statements are basically used to transfer control anywhere in the program. These include goto, return, continue and break statements. An example is given as follows : 

// Program to demonstrate the use of jump statment
#include<iostream.h>


int main()
{

    int x;
    cout<<" Enter the value of x : ";
    cin>>x; // prompts the user for input

    start : // tag for the goto statement
    cout<<" @ ";
    ++x; // prints @ until the the value of x is greated than 10
    if ( x < 10 )
    goto start; // jumps to the start tag

    // To demonstrate continue
    cout<<endl;

    while ( x > 0 )
    {
        --x; // decrements value of x

        if ( x < 10 )
        {
            cout<<" \n Hello !!!";
            continue; // continue if x is greater than 10
        }
        else
            break; // breaks the loop if x is -ve


    } // end of while
   
    return 0;
} // end of main
