Data types
In our day-to-day life, we use numbers, alphabets, words, and sentences. These can be defined as data. Again, numbers can be divided into two types: fraction and non-fraction, or integer and non-integer. Alphabets and symbols can be defined as characters. Let's look at what we call them in C, and their memory allocation. I will explain what memory allocation is and how you can find out how much memory a data type is consuming later.
Integers
Numbers that can be written without a fractional part are called integers: 5, 28, 273, 100, 986,343 are integers. There are negative integers too: -56, -87, -23,453, -1,000, and so on. They are called int in C programming. If we want to set a variable (number) equal to an integer (here, 24) we can write the following:
int number = 24;
An integer occupies 2 bytes (16 bits) or 4 bytes (32 bits) of memory depending on the processor's architecture. On 32-bit computers, an integer occupies 2 bytes of memory, and on 64-bit computers, integer occupies...
