Answer 1

#include <stdio.h>
#include <time.h>
#include <locale.h>

// locale‑aware date formatting

int main() {
    // Use the system default locale
    setlocale(LC_TIME, "");

    time_t t = time(NULL);
    struct tm *tm_info = localtime(&t);

    char buffer[128];
    strftime(buffer, sizeof(buffer), "%x", tm_info);  // %x = localized date

    printf("Localized date: %s\n", buffer);

#include <stdio.h>
#include <time.h>
#include <locale.h>

// Forcing a specific locale

int main() {
    // Forcing a specific locale
    setlocale(LC_TIME, "en_US.utf8");

    time_t t = time(NULL);
    struct tm *tm_info = localtime(&t);

    char buffer[128];
    strftime(buffer, sizeof(buffer), "%x", tm_info);  // %x = localized date

    printf("Localized date: %s\n", buffer);
