C Tutorial Part 2-Numeric Variables

 This is the second tutorial blog on C .

Today I will be discussing numeric variables.Every programming language has the ability to create and operate with numeric variables. In C, almost 80% of the logic requires the usage of different variables such as character, string, and numeric variables.

An example of using numeric variables is to add two numbers in an application.

So let's get started-

PS:You can tap or click on images to see them better.

1. Use the #include <stdio.h> header file.

2. Type int main () {}

3. Now lets type int a;

The int syntax defines or shows that the value, or values next to it are numeric variables.(a) is the variable formed. A variable in computer terms is an area in the system memory which contains a value we don't know. As this was function, their will be a semicolon in the end.

4. Write a=5;

This shows that value inside variable (a) is 5.

5. Type printf ("%d\n",a);

return 0;

We are using the printf statement to display text. %d is used to represent a numeric variable while displaying or taking input. Don't worry, the %d sign simply represents the value of (a)(after the commas), which is 5. This statement displays the value inside a, which is 5. (\n is used to leave a line)

I included return 0; as I didn't want to make this to complicated.

(return 0; closes the application).

Now simply compile and your result is below

You can also try this-

and this is the result-
