Study Notes
C Programming is a high level programming language used across various computer systems from embedded systems to supercomputers. In this language, data types such as integers, booleans, characters, strings, arrays, etc., can be declared as variables. Variables hold values which have specific properties called attributes. For example, integer numbers can only have numeric properties like size, while boolean numbers can just take two values - true and false. By declaring new variable names, you create different containers capable of holding different kinds of information. Arithmetic operators allow performing mathematical operations with these variables. These operators are addition (+), subtraction (-), multiplication (*) and division (%).
To illustrate how these concepts work together, consider the following code snippet written in C, where a, b and c represent three separate integer variables:
int a = 7;
int b = 9;
int c = a + b; // This will store the value '16' in variable 'c'.
In this example, we declare three variables a, b, and c. Then, using arithmetic operator +, we perform an addition operation between the values stored in a and b. The result 16 gets stored into variable c. Since all variables involved here are integers, they behave according to their arithmetic rules. Thus, the final value assigned to c is the sum of a and b, disregarding any decimal points that might exist in the original values.
These basic principles of working with variables and arithmetic operations form the foundation of many programs written in C, allowing developers to manipulate and process data efficiently within the constraints defined by the syntax of the language.
