- This program is created to find out the largest number among four different values using the
`if…else`

statement and prints the largest number. - Initially, four distinct numbers are stored in the variables
`n1`

,`n2 , n3`

and`n4`

. The numbers are 7.2 , -11.9 , 6.5 and 8.9. - In order to identify the largest value among these four numbers, the following
`if…else statements`

are used. - If the value in
`n1`

is greater or equal to all the values in the variable`n2`

,`n3`

and`n4`

then the value in`n1`

will be the largest and print`n1`

is the largest among all. - If the value in
`n2`

is greater or equal to all the values in the variables in`n1`

,`n3`

and`n4`

then the value is`n2`

will be the largest and print`n2`

is the largest among all. - If the value in

is greater or equal to all the values in the variables in`n3`

,`n1`

and`n2`

then the value is`n4`

will be the largest and print`n3`

is the largest among all.`n3`

- And the final else condition, that if neither the values in the variables
`n1`

,`n2`

and`n3`

are the greatest, then that consequently means that the value in`n4`

is the largest and print`n4`

is the largest among all.
