### Logic to find the Largest of two numbers

• when the user clicks on the `'LargestNo'` button, the `Largest2No()` function will get called.
• In the `Largest2No()` function, Take two numbers from the user and stored them in `n1` and` n2`.
• compare` n1` and` n2` by using the if statement i.e `if(n1>n2){ }`, if `n1` is greater than `n2` then if statement will get executed. and you will print "n1 is the largest number".
• if `n1` is less than `n2` then else part will get executed and hence you will print "n2 is the largest number".
