C++ Program for Obtaining and Displaying IP Addresses
This article was written and published to provide the code as well as a brief explanation for printing an IP address for the system. So, without further ado, let's get started.
To find and print the IP address of your computer system using C++, use a function named system() and place the command ipconfig after providing the full path of System32 i.e.,
C:\\Windows\\System32\\ipconfig
inside it, which calls the Windows Command Prompt (cmd) to find, get, and display the IP address as shown here in the following program.
C++ Programming Code to Get an IP Address
The following C++ program gets the IP address and displays it on the screen:
#include<cstdlib> int main() { system("C:\\Windows\\System32\\ipconfig"); return 0; }
When the above C++ program is compiled and executed, it will produce the following result:
Because I did not use any object or method from the "iostream" header file in the preceding program, it is not necessary to include "iostream" in the program. I thought I'd share this information because most C++ programmers, especially beginners, react negatively when they see a program that lacks a "iostream" header file 😏.
The "cstdlib" header file used in the above example contains the definitions of those functions and does the following tasks:
- process control
- memory allocation
- conversions
- and many more.
In C, we use "stdlib.h," but in C++, we use "cstdlib," which refers to the standard library of C++. Among other methods, there is a method named "system()" defined in this header file that is used to execute the system command.
When you execute the above C++ example code on your system, you will get all the "IP configuration" information of your system. However, in my case, these are the details that are relevant to this article:
