What else can I help you with?
Structure data type and elementary data type?
Both of them is very important in programming.
What is the difference between array and enum?
Array is collection of data items of same data type.Enum is collection of data items of different data type.
How can you allocate memory dynamically in c?
char* new_string; // could be any type new_string = (char*) malloc (5120); // allocate memory - typecast is necessary if (new_string == NULL) ... memory exception ... ... use the data ... free (new_string); // release memory when done
Why is data type important?
All data is stored in a computer as 0s and 1s. In order to make this more efficient, certain sets of bits can mean different things depending on what the data type is. Some languages, such as Java, make sure the programmer doesn't confuse these types and mess up the data. However, other languages allow you to do things like multiply a string and an array. If you don't pay careful attention to data types, you can easily end up with useless data.
What data type is age?
integer data type
2 reasons why using the correct field type is important?
Using the correct field type ensures accurate data entry and validation, preventing data inconsistencies or errors in the database. It also enhances data processing efficiency as the system can perform operations faster and more accurately with properly defined field types.
Structure data type and elementary data type?
Both of them is very important in programming.
What is the difference between array and enum?
Array is collection of data items of same data type.Enum is collection of data items of different data type.
Data validation best refers to?
Data Validation is a process that ensures that data entered into the database form, a web form, or a computer program conforms to the correct data type.
Why might a government intervene in the market economy?
Essentially, due to market failure of some type: the market does not efficiently allocate some desirable commodity and the government attempts to correct this misallocation.
Is data used to test a hypothesis?
It's quite possible to use all sort of data to become true a hypothesis. The problem is to find the correct type of data.
Which of these is an example of a type of technology used to collect data?
A GPS device is an example of a technology used to collect location data.
What is a type check on a database?
Checking that data types are correct for what they are needed for. If data types don't match or are of the wrong type, it can cause problems. Dates should not be stored as text for example.
Specifies the kind of data a field can contain?
A field's data type specifies the kind of data it can contain, such as text, numbers, dates, or Boolean values. This helps ensure data integrity by restricting what type of data can be entered into that field, preventing errors and inconsistencies in the database. Choosing the appropriate data type for each field is important for accurately storing and organizing data.
Which data type assigns values automatically?
None of the data types available in C assigns valur to the variable. Initially all the variables have a garbage value. But when we use calloc() to allocate memory dynamically only then it assigns NULL to the memory block assigned.

What are the quesequeses of changing the data type of field?
Changing the data type of a field can lead to data loss or data corruption if the new data type cannot accommodate the existing data. It can also affect any queries, reports, or applications that rely on the field's data type, potentially causing errors or unexpected behavior. It is important to carefully assess the impact and make any necessary adjustments to ensure data integrity before changing a field's data type.
