I don't understand why the operator static_cast<color>(1) returns 0 (see the code below).
#include <cstdio>
#include <msp430.h>
/**
* hello.c
*/
enum class color: unsigned char
{
red = 1,
green = 2,
blue = 4,
};
int main(void)
{
color c;
WDTCTL = WDTPW | WDTHOLD; // stop watchdog timer
c = color::red; printf("Red = %d\r\n", static_cast<int>(c));
c = color::green; printf("Green = %d\r\n", static_cast<int>(c));
c = color::blue; printf("Blue = %d\r\n", static_cast<int>(c));
printf("\r\n");
c = static_cast<color>(1); printf("Red = %d\r\n", static_cast<int>(c));
c = static_cast<color>(2); printf("Green = %d\r\n", static_cast<int>(c));
c = static_cast<color>(4); printf("Blue = %d\r\n", static_cast<int>(c));
printf("\r\nEnd\r\n");
return 0;
}
/*
Console:
