#include #include int main(){int x=15,y=5,z=50;printf("x=%d, y=%d, z=%d\n",x,y,z);printf("x>y? %d\n",x>y);printf("x<=y? %d\n",x<=y);printf("x+yprintf("z-30>=x+y? %d\n",z-30>=x+y);printf("y==z-30>x? %d\n",y==z-30>x);return 0;}
printf("x>y?%d\n",x>y);双引号里面的都懂吧，后面x>y是进行逻辑运算，因为x=15,y=5,所以x>y是成立的即为真，其值为1。打印结果：x>y?1
是真显示1，假显示0
