关系表达式 错误.cpp

我正在学习C编程

#include<stdio.h>   /*关系表达式*/
void main()
{
	char c='k',c1='\0';
	char x='A',y='B',z='c',w='D';  //问题?
	int i=1,j=2,k=3;
	float x=3e+5,y=0.85;
	printf("  %d %d\n",'a'+5<c,-i-2*j>=k+1);
	printf("  %d %d\n",1<j<5,x-5.25<=x+y);
	printf("  %d,%d\n",i+j+k==-2*j,k==j==i+5);
	printf("  c1=%c\n",'\0');
	printf("  x+y>z-w的值为%d",x+y>z-w); //问题?

}
