What is Address In C Programming?

In this tutorial we learn &(ampersand) means reference in c programming. Mostly it used to receive data by help of scanf() to store a particular address.

Address In C:

If you declare a variable like,

int a;

then “&a” is a address of that variable means address of memory.

Generally, we are using address number of times while declaring “scanf()” used to read the data and store in a particular memory location. Like

scanf("%d", &a);

Here, the above declaration means the value or data entered by user and store in a variable “a”, Let’s take in below Example:

//In C
#include<stdio.h>
int main()
{
  int a=10;
  printf("The address of variable a:%p\n",&a);
  printf("The value of variable a:%d\n",a);
  return 0;
}

//Output:
a=236478
a=10

Note: In each time you will get a different address to run the above code.

But In C++ case we are using the address(reference) “&” to print:

//In C++
#include<iostream>
using namespace std;
int main()
{
    int a=2;
    cout<<&a;
    return 0;
}

//Output:
0x3435fff538a4253
