Void is a data type in C language that does not refer to any value of any type. It is mostly used as the return type infunctions in C. You can declare the void pointers to take the address of variables from any data type. These pointers are often called ‘generic pointers.’ Look a...

The character data type is represented by the char keyword and is used to store a variable with only a single character. The size of the char data type is 1 byte (i.e., 8 bits). It has two subtypes- signed char and unsigned char. The range for these is -127 to 128 and 0 to ...

intrepresentsinteger, it can be used to declare an integer type variable, constant in C language. It takes either2 bytes (16 bits)or4 bytes (32 bits)according to compiler architecture in the computer memory. It stores only integer numbers (numbers without precision). The value range of 2 ...
Pythonis another high-level language that supports multiple data types. Eight data types that are built in by default include text, numeric, sequence, mapping, set, Boolean, binary and none. To set a data type, a programmer simply assigns a value to a variable: ...
Enumeration types are built up from explicitly defined values. This is to say that there is no natural range such as integers which have a fixed pattern between any two values. As a simple example, let's look at the intrinsic (built into the language) VHDL type of the bit. A “bit”...
DAX functions never take a cell reference or a range as reference, but instead DAX functions take a column or table as reference. DAX date and time functions return a datetime data type. In contrast, Excel date and time functions return an integer that represents a date as...
