Priniting Sum of Numbers using Goto Statement in C++

This program calculates the sum of all the natural numbers from a given value down to 1 using a goto statement. Here's how the program works:

It prompts the user to enter a value.
It reads the value into the variable a.
It initializes the variable n to 0.
It uses a goto statement to create a loop that adds the value of a to n and decrements a by 1.
It checks if a is greater than or equal to 0. If it is, the loop goes back to the start label and repeats. If it is not, the loop exits.
It prints the total value of n.
The program ends.

While this program works correctly, using a goto statement is generally not considered good programming practice because it can make the code difficult to read and maintain. A better alternative would be to use a while or for loop to calculate the sum.

Source Code

#include<iostream>
using namespace std;
int main()
{
    int a,n=0;
    cout<<"\nEnter the value :";
    cin>>a;
    start:
    n=n+a;
    a--;
    if(a>=0)
        {
            goto start;
        }
    cout<<"\nTotal value :"<<n;
    return 0;
}
