What is Cloud computing?

Cloud computing refers to the delivery of computing resources and services over the internet, allowing users to access and use applications, storage, and processing power without the need for local infrastructure or hardware. It involves the use of remote servers, typically hosted in data centers, to store, manage, and process data instead of relying on a local computer or server.


In cloud computing, users can access a wide range of services and resources on-demand, which are usually provided by a cloud service provider (CSP). These services can include infrastructure resources (such as virtual machines, storage, and networking), platforms for developing and deploying applications, and software applications that can be accessed and used via the internet.


Cloud computing offers several advantages over traditional on-premises computing models. It allows for scalability, where users can easily scale up or down their resource usage based on their needs, without having to invest in and manage physical infrastructure. It also enables flexibility and mobility, as users can access their applications and data from any device with an internet connection. Additionally, cloud computing offers cost efficiency since users only pay for the resources they consume, avoiding upfront hardware and maintenance costs.


Some popular examples of cloud computing services include Amazon Web Services (AWS), Microsoft Azure, Google Cloud Platform (GCP), and Salesforce.com. These providers offer a wide range of services to cater to various needs, from hosting simple websites to running complex big data analytics or artificial intelligence applications.

C Program to Find GCD of two Numbers

There are many ways to find the greatest common divisor in C programming. Example #1: GCD Using for loop and if Statement # include <stdio.h> int main () { int n1, n2, i, gcd; printf ( "Enter two integers: " ); scanf ( "%d %d" , &n1, &n2); for (i= 1 ; i <= n1 && i <= n2; ++i) { // Checks if i is factor of both integers if (n1%i== 0 && n2%i== 0 ) gcd = i; } printf ( "G.C.D of %d and %d is %d" , n1, n2, gcd); return 0 ; } Example #2: GCD Using while loop and if...else Statement # include <stdio.h> int main () { int n1, n2; printf ( "Enter two positive integers: " ); scanf ( "%d %d" ,&n1,&n2); while (n1!=n2) { if (n1 > n2) n1 -= n2; else n2 -= n1; } printf ( "GCD = %d" ,n1); return 0 ; } Output Enter two positive integers:
