The ‘void’ data type
The void data type, in simple words, means ‘nothing’. This data type either explicitly declares a function that doesn’t return any value or creates generic pointers. There are different functions available in C programming that do not return any value.…
The ‘char’ data type in C
In C programming, the char data type comes handy for storing characters like letters and punctuation marks. However, from a technical point of view, it is an integer type, because the char type actually stores integer values, not characters. To…
