What is the difference between an 'int' and 'float' in C?

• A. 'int' is for numbers with decimal points
• B. 'float' is for whole numbers
• C. 'int' is used for whole numbers, while 'float' is for numbers with decimal points
• D. There is no difference; they are the same

Answer: (C)

The distinction between 'int' and 'float' in C programming is fundamental to understanding data types and how they are used to represent numerical values. The 'int' data type is designated for representing whole numbers or integers. This means that any value stored in an 'int' variable will not have any fractional or decimal part; it can only be positive or negative whole values, including zero. On the other hand, the 'float' data type is specifically intended for representing real numbers and can store values that include decimal points. This capability allows for the representation of fractions and values that require a greater range of precision, such as 3.14 or -0.001, which would not be possible with an 'int'. Thus, knowing that 'int' handles whole numbers and 'float' caters to values with decimal points is crucial for effective data manipulation and type selection in C programming. This understanding helps programmers utilize the right data type for the operations they intend to perform, ensuring accuracy and proper memory utilization.
