Example: Custom Character Sales Bar Chart in C

// Custom Character Sales Bar Chart
#include <stdio.h>
#include <string.h> // Required for strlen in some scenarios, though not strictly here for basic char

int main() {
    // Step 1: Define product names and sales data
    char *products[] = {"Quarter 1", "Quarter 2", "Quarter 3", "Quarter 4"};
    int sales[] = {25000, 32000, 18000, 40000};
    int num_products = sizeof(sales) / sizeof(sales[0]);

    // Step 2: Define custom bar character and legend
    char bar_char = '#';
    int unit_per_char = 1000; // Each '#' represents 1000 units of sales

    // Step 3: Print Chart Header and Legend
    printf("--- Sales Performance by Quarter ---\n");
    printf("Legend: Each '%c' represents %d units of sales\n", bar_char, unit_per_char);
    printf("-------------------------------------\n");

    // Step 4: Iterate through products and print bars
    for (int i = 0; i < num_products; i++) {
        printf("%-12s | ", products[i]); // Print quarter name
        
        // Step 5: Calculate number of bar_chars and print
        int bar_length = sales[i] / unit_per_char;
        for (int j = 0; j < bar_length; j++) {
            printf("%c", bar_char);
        }
        printf(" (%d)\n", sales[i]); // Print actual sales value
    }
    printf("-------------------------------------\n");
