Addition of Two Numbers in C
Let’s find the sum of two values stored in variables num1 and num2:
#include <stdio.h>
int main(){ // Declare variables int num1,num2,sum;
printf("Enter two integers: ");
scanf("%d %d", &num1, &num2);
// calculate the sum of two numbers
sum = num1 + num2;
// Print the result
printf("%d + %d = %d", num1, num2, sum); return 0;}
Output :
Enter two integers: 10 20 10 + 20 = 30
Analogy Based Example: Addition of Two Numbers in C
Problem Statement: Online Shopping Cart Item Counter
Background: These days, with online shopping, folks fill their carts on websites. They like to see how many items they’ve chosen. It helps them decide what to get, see how much they’re buying, and check they didn’t forget or double-add anything.
Objective: Develop a program that simulates adding items to an online shopping cart. The program should:
- Represent individual items as variables.
- Add the items together to get a total count.
- Display the total number of items in the cart to the user.
Constraints:
- For simplicity, count each item as one unit regardless of its type (e.g., shoes, shirt).
- Write the program in C programming language.
- The output should clearly indicate the total number of items in the cart.
Expected Outcome: Upon execution, the program should provide a clear and concise output indicating the total number of items in the online shopping cart.
#include <stdio.h>
int main() { // Imagine you're shopping online. // You add a pair of shoes to your cart. int shoes = 1;
// Then, you add a shirt to your cart. int shirt = 1;
// Now, let's see how many items you have in total in your cart. int totalItems = shoes + shirt;
// Print the total number of items in the cart. printf("Total items in the cart: %d", totalItems);
return 0;}
Output :
Total items in the cart: 2
When you run this code, it will output: Total items in the cart: 2
In this example, the variables shoes and shirt represent the individual items you added to the cart. The addition operation (shoes + shirt) calculates the total number of items, and the result is printed out using the printf function.
