Discrete variables are countable in a finite amount of time.
So, counting a number of students in a class is an example of discrete variable.
Because we can easily count the number of students in a class.

Discrete variables are countable in a finite amount of time.
So, number of chocolates in a box is an example of discrete variable.
Because we can easily count the number of chocolate in a box.

A discrete variable is a variable whose value is obtained by counting.
So, discrete variables measured with enough precision can often be considered continuous for practical purposes.
Example: number of students absent in a class.

Continuous variable has the infinite set of the data.
Example: Time taken to write a homework.

A continuous variable is a variable whose value is obtained by measuring.
So, the length of someone's foot is an example of continuous variable.

Continuous variable has the infinite set of the data.
So, are you a girl or boy is not an example of continuous variable.

A continuous variable is a variable whose value is obtained by measuring.
So, The weight of students in a class is an example of continuous variable.

A discrete variable is a variable whose value is obtained by counting.
So, height of animals in a park is not a discrete variable. 
Because the height will not be same for all animal, it may varying in height. 
example: elephant - $4$ m, tiger - $2$ m, giraffe - $10$ m

A discrete variable is a variable whose value is obtained by counting.
So, number of bubbles in a fish tank is countable.

A continuous variable is a variable whose value is obtained by measuring.
Example: The weight of a cat is a continuous variable as it can take any value - for example, $2$ kg, $4$ kg, $3.2$ kg etc.
