- Instruct the user to Enter two number for calculation
- The first Number entered by user convert into int and assigned to the First variable
- The Second Number entered by user convert into int and assigned to the second variable
- Instruct the user to Enter their choice to perform the calculation
- The choice entered by the user assigned to the choice variable
- When statement result based on user choice assigned to result variable
- Operation addition is performed if the user enters “A” or “a”
- Operation subtraction is performed if the user enters “S” or “s”
- Operation multiplication is performed if the user enters “M” or “m”
- Operation Division is performed if the user enters “D” or “d”
- if Enter wrong input mentioned in 7,8,9,10 then else part execute
- Finally, Result is print on command prompt
