  Conditional Rendering in React Conditional Rendering is one of the most useful concepts in React. It means showing different content on the screen depending on a condition. For example: If a user is logged in → show Logout If a user is not logged in → show Login If a student has passed → show Congratulations If a product is available → show Buy Now If data is loading → show Loading... React does not have a separate if rendering tag. Instead, we use normal JavaScript conditions such as if, the ternary operator, &&, and switch to decide what should appear in the UI.

scanf("%d%d", &V, &W);


 two integers from keyboard input and stores them in V and W. %d matches integers and & passes the variable's address so scanf can store values there 

Step :7

sum = V + W;
Adds the twos values and assigns the result to sum

Step :8

printf("sum %d", sum);

Displays the sum. Typically, you'd write printf("sum = %d", sum); to improve readability
