Types of Data type: 1. int Data type int Datatype is used to store integer numbers into computer memory. int data type allocates 4 bytes in a memory to store an integer value. For example 6 . Number 6 is an integer number. Integer does not contain point.  2. float Data type float data type is used to store real numbers into computer memory. float data type allocates 8 bytes in a memory to store real number.

Introduction to C Programming Language What is C language? C is a high-level programming language. C programming language was designed and developed by Denis Ritchie  at AT&T Bell Laboratoires in 1972-73. C language is a case-sensitive language, which means  num  is not equal to Num , they both are different from each other. C is an easy to learn programming language. Similarities between learning English Language and C Programming Language: 1) English language: First we have to learn Alphabets in English language.     C language: First we have to learn Alphabets, Digits and Special Symbols in C language. 2) English language: After learning Alphabets, we learn to create words.     C language: After learning  Alphabets, Digits and Special Symbols, we learn to create Variable and Constants and learn what are keywords in C language 3) English language: After creating words, we learn how to make a sentence using those words.     C ...
