Example: Dynamic Scaling Sales Bar Chart in C

// Dynamic Scaling Sales Bar Chart
#include <stdio.h>

int main() {
    // Step 1: Define product names and sales data
    char *products[] = {"Electronics", "Clothing", "Books", "Home Goods", "Groceries"};
    int sales[] = {1200, 850, 300, 950, 1500};
    int num_products = sizeof(sales) / sizeof(sales[0]);

    // Step 2: Find the maximum sales value
    int max_sales = 0;
    for (int i = 0; i < num_products; i++) {
        if (sales[i] > max_sales) {
            max_sales = sales[i];
        }
    }

    // Step 3: Define a maximum bar width and calculate scaling factor
    int max_bar_width = 40; // Max number of asterisks for the longest bar
    double scale_factor = (double)max_bar_width / max_sales; // Units per asterisk

    // Step 4: Iterate through products and print scaled bars
    printf("--- Dynamic Scaling Sales Bar Chart ---\n");
    for (int i = 0; i < num_products; i++) {
        printf("%-15s | ", products[i]); // Print product name
        
        // Step 5: Calculate number of asterisks based on scaling factor
        int bar_length = (int)(sales[i] * scale_factor);
        for (int j = 0; j < bar_length; j++) {
            printf("*");
        }
        printf(" (%d)\n", sales[i]); // Print actual sales value
    }
    printf("---------------------------------------\n");

    return 0;
