#Added Inputting a variable functionality

Types of Changes

• Bux Fix
• [ x] Added new feature

Please describe the changes you have made, be as descriptive as you can

I have added a feature to input a single variable only.
If user is trying to get input of an uninitialized input then in converted code the variable automatically gets converted to 'float' datatype.

If you have added any new feature please add screenshot of the output, how it has been changed after addition of the new feature

This code can be altered a little to include multiple variables in a single input statement by using a queue.

A few changes before we merge this PR - look at the comments

[sumanthd17]

instead of having 2 lines for initializing and then taking input i feel it is better to do it in the same line.
Eg. input int a;
We then initialize the variable a and take the input. This way we can initialize any type of variable.

I would love to work on this issue after this PR is merged.There is no point of adding features if it is not merge at the end.
Btw, thanx for your suggestion and will look forward for your suggestions and reviews in future.
