int x,y,z;x=y=z=3;y=x++ -1;printf("%d\t%d\t",x,y);y=++x -1;printf("%d\t%d\t",x,y);y=z-- +1;后面还跟着y=z--+1;printf("%d\t%d\t",z,y);y=--z+1;printf("%d\t%d\t",z,y);求答案和分析.

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)= 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( int x=1,y=2,z=3; x=x^z; y=y^z; z=x^y; cout 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=10,y=3,z; cout int x=0;y=0;z=0;x=(y=3;z=5*y,y=10);x=?y=?z=? C语言：int x=5,y=7,z; z=x>y?5>3?++x+y:x:++x-y++ 则z的值为________. int x=1,y=2,z=3;求z+=x>y?++x：++y 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) X+Y+Z=? x/y=(x+z)/(y+z)y/z=(x+y)/(x+z) #includemain(){int x=1,y=2,z=3;if(x>y)if(y int x=1,y=2,z=3if (x>y)if(y x+=y+=z; printf(%d ,z+=x>y?x++:y++);过程是怎么的?int x=1,y=2,z=3;x+=y+=z;printf(%d ,z+=x>y?x++:y++);x=y=z=-1;(++x||(++y&&++z));printf(%d %d %d ,x,y,z); 已知 x/(y+z)+y/(z+x)+z/(x+y)=1求 (x*x)/(y+z)+(y*y)/(x+z)+(z*z)/(x+y)=?
