Programm to get multiplication table

Description:

This program take a number as input and make its multiplication table automatically.

Code:


#include<iostream>
#include<conio.h>
#include<iomanip>
#include<math.h>
using namespace std;
int main()
{
    int i,n=1,p;
    xy:
    cout<<"Enter the number to get its multiplication table"<<endl;
    cin>>n;
    cout<<endl;
    i=1;
    while(i<=10)
    {p=n*i;
     cout<<n<<"*"<<i<<"="<<p<<endl;
     i++;
     }
     goto xy;
     getche();
     return 0;
     }

Output:

Addition and Multiplication of Two Numbers

Description:

In c++ 'goto' operator is used to repeat program again. In other words it acts as infinite loop.

Code:


#include<iostream>
#include<conio.h>
#include<iomanip>
using namespace std;
int main()
{
    int a,b,c,d;
    xy:
    cout<<"Enter two numbers to get their sum and product"<<endl;
    cout<<"Enter the value of a"<<endl;
    cin>>a;
    cout<<"You have entered a="<<a;
    cout<<endl<<"Enter the value of b"<<endl;
    cin>>b;
    cout<<"You have entered b="<<b<<endl;
    c=a+b;
    cout<<"The sum of a and b is"<<endl<<"a+b="<<c<<endl;
    d=a*b;
    cout<<"The product of a and b is"<<endl<<"a*b="<<d<<endl;
    goto xy;
    getche();
    return 0;
    }

Output:
