Artificial intelligence has moved beyond simply answering questions and generating text. A new generation of AI systems—known as AI agents—is emerging with the ability to plan tasks, use tools, make decisions, and complete multi-step workflows with less human intervention. From managing emails and analyzing data to writing software and assisting customers, AI agents could significantly change how people work. What Are AI Agents? An AI agent is a software system that can perceive information, reason about a goal, take actions, and adapt based on the results. Traditional AI tools usually respond to a specific instruction. For example, you might ask an AI chatbot to summarize a document, and it provides a summary. An AI agent can go further. You could give an agent a goal such as: "Research three competitors, compare their pricing, summarize their main features, and prepare a report." The agent may then: 1) Understand the objective. 2) Break the task into smaller steps. 3) Searc...
C program to find sum of digits of a number using recursion. #include <stdio.h> int sumOfDigits(int num); int main() { int num, sum; printf("Enter a number: "); scanf("%d", &num); sum = sumOfDigits(num); printf("The sum of digits of %d is %d.\n", num, sum); return 0; } int sumOfDigits(int num) { if (num == 0) { return 0; } else { return (num % 10) + sumOfDigits(num / 10); } } Explanation : The program starts by including the standard input-output library stdio.h. The program defines a function sumOfDigits that takes an integer argument num and returns the sum of its digits. The function is defined using recursion. Inside the sumOfDigits function, there is an if statement that checks if the number num is equal to 0. If it is, the function returns 0 as the sum of digits. If num is n...
