Sure, let's talk about memory addresses in C using simple language:
Think of memory in a computer as a big collection of boxes where you can store information. Each box has its own unique address, just like houses on a street. Similarly, in programming, every piece of data (like variables or arrays) has its own address in the computer's memory.
In C, you can find the memory address of a variable using the address-of operator (&). This operator returns the memory address of a variable.
Example
Let's say we have a variable x in our program. We can find its memory address like this:
#include <stdio.h>
int main() {
int x = 10; // Declare and initialize a variable 'x' with a value of 10
// Print the memory address of 'x'
printf("The memory address of variable 'x' is: %p\n", (void*)&x);
return 0;
}
In this example
x and assign it a value of 10.&x to get the memory address of x.%p format specifier, which is used for printing memory addresses. We also cast the result of &x to (void*) type because %p expects a pointer to void.When you run this program, it will print out the memory address of the variable x.
Memory addresses are important because they allow us to access and manipulate data stored in memory, especially when dealing with pointers and dynamic memory allocation.
