int main(int argc, char **argv)
{
    char c = 'a';
    int i = 100;
    float f = 21.76;
    double d = 7263428734.7464;

    printf("c = %c\n", c);
    printf("i = %d\n", i);
    printf("f = %f\n", f);
    printf("d = %lf\n", d);
    
    printf("f(.2f) = %.2f\n", f);
    printf("d(.4lf) = %.4lf\n", d);
    
    printf("c = %c : i = %d : f = %f : d = %lf\n", c, i, f, d);

    return 0;
}
