c++中double x; int a; a=x=(a=5,5/2.

c++中double x; int a; a=x=(a=5,5/2. double f(double x); {double a=0;int i; for (i=0;i C语言中!a怎么理解#includevoid main(){ int a=4;int b=5;int x=2; int double x=2.5 ; int a=7 ;double y=4.7 x+a%3*(int)(x+y)%2/4 该表 已知int k,a,b;unsigned long w=5; double x=1.42;下列表达式不符合C语言语法的是 int k,a,b; unsigned long w=5; double x=1.42; 则下面不符合c语言的表达式是 #include main() {int a=325;double x=3.1415926; printf("a=%+0 func(int a,int b) {int c; c=a+b; return(c); } main() {int x= fun(int x,int y,int z) {z=x*x+y*y;} main() {int a=31; fun(5, 1、设有说明,int a=7;double x=2.5,y=4.7;",则表达式x+a%3*(int)(x+y)%2/4 3、以下正确的函数定义是( ).A.double fun(int x,int y); {int z; z=x+y; re 在C中,有以下定义：int a;long b;double x,y;则以下选项中正确的表达式是 （A) a%(int)(
