用C++编写的一个编译器

int printf(char * format, ...);
int main()
{
	int a=7, b=3;
	printf("a=7, b=3\n\n");
	printf("!a =%d\n", !a);
	printf("~a =%d\n", ~a);
	printf("a++ =%d\n", a++);
	printf("++a =%d\n", ++a);
	printf("a-- =%d\n", a--);
	printf("--a =%d\n", --a);
	printf("sizeof(a) =%d\n",sizeof(a));
	printf("a*b =%d\n", a*b);
	printf("a/b =%d\n", a/b);
	printf("a%%b =%d\n", a%b);
	printf("a+b =%d\n", a+b);
	printf("a-b =%d\n", a-b);
	printf("a<<b =%d\n", a<<b);
	printf("a>>b =%d\n", a>>b);
	printf("a>b =%d\n", a>b);
	printf("a>=b =%d\n", a>=b);
	printf("a<b =%d\n", a<b);
	printf("a<=b =%d\n", a<=b);
	printf("a==b =%d\n", a==b);
	printf("a!=b =%d\n", a!=b);
	printf("a&b =%d\n", a&b);
	printf("a^b =%d\n", a^b);
	printf("a|b =%d\n", a|b);
	printf("a>b?a:b =%d\n", a>b?a:b);
	return 0;
