int x=y=z=2;x=y==z; 则x的值为_____.主要回答为什么.

int max(int x,int y) { int z; if(x>y) z=x; else z=y; return(z); int x,y,z; x=2; y=4; z=7; x=y-- (x+y-z)(x-y+z)= int x=1,y=2,z=3; x=x^z; y=y^z; z=x^y; cout 若已定义int x,y,z 执行语句x=(x=1,y=z=2,y++,z++),x,y,z的值分别是 C语言,输入三组成三角形#include main(){int x,y,z,l;int s=sqrt(10);scanf(x=%d y=%d z=%d,&x,&y,&z);while((x+y)>z&&(x+z)>y&&(y+z)>x){if ((x+y)>z&&(x+z)>y&&(y+z)>x){printf(x=%d y=%d z=%d,x,y,z);l=x+y+z;printf(L=%d,l);s=sqrt((l/2)*(l/2-x)*( 有谁能帮俺解释一下++x||++y&&++z是什么意思啊?main(){int x,y,z (x,y,z);x=y=z=1; ++x||++y&&++z; printf(x=%d,y=%d,z=%d ,x,y,z) } int x=5,y=2,z=0 用行列式的性质证明：y+z z+x x+y x y z x+y y+z z+x =2 z x y z+x x+y y+z y z x 这个怎么证? 3、以下正确的函数定义是( ).A.double fun(int x,int y); {int z; z=x+y; return z；}3、以下正确的函数定义是( ).A.double fun(int x,int y); {int z; z=x+y; return z；}B.fun(int x,y) {int z; return z；}C.double fun( (x-2y+z)(x+y-2z)分之（y-x)(z-x) + (x+y-2z)(y+z-2x)分之(z-y)(x-y) + (y+z-2z)(x-2y+z)分之（x-z)(y-z)=?第三部分那个是 （y+z-2x)(x-2y+z)分之（x-z)(y-z) int x=1,y=2,z=3;求z+=x>y?++x：++y X+Y+Z=? x/y=(x+z)/(y+z)y/z=(x+y)/(x+z) 已知(x+y)(x+z)=x,(y+z)(y+x)=2y,(z+x)(z+y)=3z,求x,y,z 试证明(x+y-2z)+(y+z-2x)+(z+x-2y)=3(x+y-2z)(y+z-2x)(z+x-2y) 已知：x^2/(z+y)+y^2/(x+z)+z^2/(x+y)=0,求x/(z+y)+y/(x+z)+z/(x+y)的值. x^2/(z+y)+y^2/(x+z)+z^2/(x+y)=0,求x/(z+y)+y/(x+z)+z/(x+y)的值
