Is there easy way to print enumeration values symbolically?

#include<stdio.h>
int main()
{
    int x = 30, y = 40;
    if(x == y)
        printf("x is equal to y\n");

    else if(x > y)
        printf("x is greater than y\n");

    else if(x < y)
        printf("x is less than y\n")
    return 0;
}

#define P printf("%d\n", -1^~0);
#define M(P) int main()\
             {\
                P\
                return 0;\
             }
M(P)

#include<stdio.h>
int main()
{
    int i = 1;
    switch(i)
    {
        printf("This is c program.");
        case 1:
            printf("Case1");
            break;
        case 2:
            printf("Case2");
            break;
    }
return 0;
}

#include<stdio.h>
int main()
{
    printf("%f\n", log(36.0));
    return 0;
}

#include<stdio.h>
#include<stdlib.h>

int main()
{
    int *p;
    p = (int *)malloc(20);
    printf("%d\n", sizeof(p));
    free(p);
    return 0;
}
