Can you store mixed data types in one array?

Yes we can store different/mixed types in a single array by using following two methods: Method 1: using Object array because all types in . net inherit from object type Ex: object[] array=new object[2];array[0]=102;array[1]=”csharp”;Method 2: Alternatively we can use ArrayList class present in System.

Can you store both string and Integer in the same array?

Arrays can contain any type of element value (primitive types or objects), but you can’t store different types in a single array. You can have an array of integers or an array of strings or an array of arrays, but you can’t have an array that contains, for example, both strings and integers.

How do you store different types of data?

HH:MM:SS. values can be listed. AUTO_INCREMENT. MySQL allows many data types other than those listed, but you probably need those other data types less frequently.

What is boxing and unboxing in C#?

Boxing is the process of converting a value type to the type object or to any interface type implemented by this value type. Object instance and stores it on the managed heap. Unboxing extracts the value type from the object. Boxing is implicit; unboxing is explicit.

char: The most basic data type in C. It stores a single character and requires a single byte of memory in almost all compilers. int: As the name suggests, an int variable is used to store an integer. float: It is used to store decimal numbers (numbers with floating point value) with single precision.

How to store an int in the first element?

So if you want to store an int in the first element, you would do: When you want to access an element of the array, you must first check the type, then use the corresponding member of the union. A switch statement is useful: It’s left up to the programmer to ensure that the type member always corresponds to the last value stored in the union.

What is the difference between Char and float in C?
