Question

Should variables that contain numbers always be declared as integer or floating-point data types? Why or why not? Name potential examples

Answer 1

Should variables that contain numbers always be declared as integer or floating-point data types:

Answer: No. Variables that contain numbers can be declared other than integer or floating-point data types.

Description:

• Data types that can contain numeric values are:

• char
• short
• int
• long
• float
• double

• Example:

• Char data type can also contain numbers and that will return output as the ASCII value associated with that number.

Output:

Here, variable a will return ASCII value associated with number 80 that is P and variable b will return ASCII value associated with number 100 that is d.

• One can also declare numbers with following data type:

short a = 80;

long a = 80;

double b = 80.80;

long double b = 80.0080;
