Understanding the Long Data Type in C

The long data type in C is primarily designed to store larger integer values compared to the standard int data type. It allows programmers to work with integers that are larger than the standard size provided by an int, which is especially useful in situations where large numerical calculations or data storage is necessary.

Analysis of Options

1. Small integers: This is incorrect. long is not typically used for small integers, as the int type suffices for such cases.

2. Single-precision floating-point values: This is also incorrect. Single-precision values are represented using the float data type in C, not long.

3. Large integers: This is correct. long is meant for storing larger integer values and can accommodate a wider range than the standard integer types.

4. Double-precision floating-point values: Incorrect as this type is represented by the double data type, not long.

Conclusion

Given the analysis above, the correct option that reflects the purpose of the long data type is:

• Large integers.

This data type can store integer values that exceed the limits of the typical int, making it an essential part of handling larger numerical data in C programming.
