VARIABLES EXAMPLE IN C LANGUAGE

Simple example to explain how variables are used.

Syntax:

int num;

float decimal;

char alphabet;

double number;

Here int, float, char and double are datatypes(type of data).

Here num,decimal,alphabet, number are variables. They may have any name.

Example describes getting two values from user and their addition .

#include<stdio.h>

int main()

{

int num1,num2;// Global declaration

printf("Enter the first number");

scanf("%d",&num1);

printf("Enter second number");

scanf("%d",&num2);

add(num1,num2);//Passing value to a  function "add()"

return 0;

}

void  add(int x,int y)

{

int total; // local variable

total = x + y; // performing actual addition

printf("The addition of two number is: %d",total); //Displaying addition of two numbers on screen

}

Output:

The addition of two number is: 5

Description:

Here we have used two types of variables.

1.Local variable (ex : total,x,y...)

2.Global variable (Ex: num1,num2)

We make those variable as global variable which we need to use throughout the code.

We make those variables as local variable which we would require very few times.
