Initialize values of an enum:

    INFO = 20,
    WARNING = 30,
    ERROR = 40,
    CRITICAL = 50,
};

Examples ​

c
#include <stdio.h>

enum Bool {
    FALSE,  // 0
    TRUE,   // 1
};

enum Log {
    DEBUG = 10,
    INFO = 20,
    WARNING = 30,
    ERROR = 40,
    CRITICAL = 50,
};

int main() {
    printf("Bool TRUE = %d\n", TRUE);
    printf("Log ERROR = %d\n", ERROR);
    enum Log active_log = INFO;
    printf("Active log level = %d\n", active_log);
    return 0;
}
