To determine the data type of the number [tex]\(-7\)[/tex], examine the number more closely.
1. float: A float is used to represent numbers that have a decimal point, such as [tex]\(7.5\)[/tex] or [tex]\(-3.14\)[/tex]. Since [tex]\(-7\)[/tex] does not have a decimal point, it is not a float.
2. single: In the context of data types, 'single' typically isn't a standard type in most common programming languages' terminology for basic types. Therefore, [tex]\(-7\)[/tex] isn't classified as 'single'.
3. sting: This option seems to be a typo or misprint of 'string'. A string is a sequence of characters and is usually enclosed in quotes (e.g., "hello" or "123"). Since [tex]\(-7\)[/tex] is not enclosed in quotes and is intended to be a numerical value, it is not a string.
4. int: An int, or integer, is a data type used to represent whole numbers without any decimal points. Examples include [tex]\(-7\)[/tex], [tex]\(0\)[/tex], and [tex]\(42\)[/tex]. Since [tex]\(-7\)[/tex] is a whole number and fits this description perfectly, it is classified as an integer.
Based on the above analysis, the data type of [tex]\(-7\)[/tex] is int. Therefore, the correct choice is the fourth option, int.
