List and briefly describe the variable types used in C.
What will be an ideal response?
Int: Use this variable type for an integer (positive or negative number).
Float: This variable type is for a real number that includes a decimal point, such as 1.299999.
Double: Use this variable type for a double-precision floating point.
Char: This variable type holds the value of a single letter.
String: This variable type holds the value of multiple characters or words.
Const: A constant variable is one you create to hold a value that doesn't change for the duration of your program. For example, you can create a constant variable called TAX and give it a specific value: const TAX - .085. If this variable is used in areas of the program that calculate total costs after adding an 8.5% tax, it's easier to change the constant value to a different number if the tax rate changes, instead of changing every occurrence of 8.5% to 8.6%.
