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...
Data types are fundamental in computer programming because they enable a programmer to determine the type of data that is being utilized and saved precisely. Some typical examples are- integers (whole numbers), floating point numbers (numbers with decimals), strings, etc. The storage method and ...
There are several new elements of C in this program: Notice that the code uses a new kind of variable declaration. The previous examples just used an integer variable type (int), but this one adds a floating-point variable type (float) so that you can handle a wider variety of data. ...

Data types define the size and type of values to be stored in the computer memory, Basic Data Types are also known as "primitive data types" here are the few basic data types with their sizes in C language:char int float1) char
What is a data type in programming? In any programming language, the data type defines which operations can safely be performed to create, transform and use the variable in another computation. Specifically, every piece of data has a type that tells the machine how to interpret its value. ...

We do this in C by explicitly assigning a data type to the data we want to manipulate. C is a strongly typed language. That is, every value must have a type associated with it. It should be noted that some languages infer the type of a piece of data by how it is used. They ...
