Please tell the answer

Answer 1

1.Integers and floats are two different kinds of numerical data. An integer (more commonly called an int) is a number without a decimal point. A float is a floating-point number, which means it is a number that has a decimal place. Floats are used when more precision is needed

2.A character constant like '!' represents a single character. A string literal between double quotes usually represents multiple characters. A string literal like "!" seems to represent a single character, but it actually contains two: the ! you requested, and the \0 which terminates all strings in C.
