// Decimal to Hexadecimal using sprintf
#include <stdio.h> // Required for printf and sprintf

int main() {
    // Step 1: Declare variables for decimal input and hexadecimal output string
    int decimalNum;
    char hexString[20]; // Buffer to store the hexadecimal string

    // Step 2: Prompt user for input
    printf("Enter a decimal number: ");
    scanf("%d", &decimalNum);

    // Step 3: Use sprintf to convert decimal to hexadecimal string
    // %X format specifier converts an integer to uppercase hexadecimal.
    // %x converts to lowercase hexadecimal.
    sprintf(hexString, "%X", decimalNum);

    // Step 4: Print the original decimal number and its hexadecimal equivalent
    printf("Decimal %d is Hexadecimal %s\n", decimalNum, hexString);

    return 0;
