为什么无法进行X2,X3的值的运算,得不到X2X3,输出是空的
#include <stdio.h>
#include <stdlib.h>
#include <math.h>
/* run this program using the console pauser or add your own getch, system("pause") or input loop */
int main()
{
double a,b,c,d,e,f,x2,y3;
printf("Enter Frist X:");
scanf("%lf",&a);
printf("Enter Frist Y:");
scanf("%lf",&b);
printf("Enter Frist Result:");
scanf("%lf",&c);
printf("Enter Next X:");
scanf("%lf",&d);
printf("Enter Next Y:");
scanf("%lf",&e);
printf("Enter Next Result:");
scanf("%lf",&f);
x2= (ed-bf) /(ad-bc);
y3= (af-ec) /(ad-bc);
printf("X: \n",x2);
printf("y: \n",y3);
return 0;
}
