C Exercises: New item price and increased price according to the item price table

Last update on September 19 2025 12:45:02 (UTC/GMT +8 hours)

Revise an item's price based on a price table

Write a C program that reads the item's price and creates a revised price for the item, based on the item price table.

Item Price	Increase Rate
100 - 400.00	14%
400.01 - 800.00	11%
800.01 - 1200.00	9%
1200.01 - 2000.00	6%
Above 2000.00	3%

Sample Solution:

C Code:

#include <stdio.h>
int main () 
{
    // Declare variables for item price and increased price
    float price, increased_price;

    // Prompt the user to input the item price
    printf("Input the item price:");

    // Read the input value for item price
    scanf("%f", &price);

    // Check the range of the item price and calculate increased price and percentage accordingly
    if (price >= 100 && price <= 400){

        // Calculate increased price and update item price
        increased_price = price * 0.14;
        price = price + increased_price;

        // Print the new item price, increased price, and increase percentage
        printf("New Item price: %.2f\n", price);
        printf("Increased price: %.2f\n", increased_price);
        printf("Increase Percentage: 14%%\n");
    }
    else{

        if (price > 400 && price <= 800){

            increased_price = price * 0.11;
            price = price + increased_price;

            printf("New Item price: %.2f\n", price);
            printf("Increased price: %.2f\n", increased_price);
            printf("Increase Percentage: 11%%\n");
        }
        else{

            if (price > 800 && price <= 1200){

                increased_price = price * 0.09;
                price = price + increased_price;

                printf("New Item price: %.2f\n", price);
                printf("Increased price: %.2f\n", increased_price);
                printf("Increase Percentage: 9%%\n");
            }
            else{

                if (price > 1200 && price <= 2000){
                    increased_price = price * 0.06;
                    price = price + increased_price;

                    printf("New Item price: %.2f\n", price);
                    printf("Increased price: %.2f\n", increased_price);
                    printf("Increase Percentage: 6%%\n");
                }
                else{

                    increased_price = price * 0.03;
                    price = price + increased_price;

                    printf("New Item price: %.2f\n", price);
                    printf("Increased price: %.2f\n", increased_price);
                    printf("Increase Percentage: 3%%\n");
                }
            }
        }
    }
}

Sample Output:

Input the item price:525
New Item price: 582.75
Increased price: 57.75
Increase Percentage: 11%
