翻译过来是，非法的操作数，为二元操作符/，int *和int 意思是，int */int这种除法操作是不合法的。出错的一行是p=(p1+p2)/2，不知道指针除以2是要做什么呢？p=(p1+p2)/2; 地址与地址不能相加p = (p2 - p1)/2 + p1 就行了
C Bitwise Operators& binary bitwise AND ^ binary bitwise exclusive OR (XOR) | binary bitwise inclusive OR ~ unary bitwise complement (NOT)An operand is the variable or value on which the operator acts. Bitwise operators perform the given operation on each bit in the operand. Binary means the...
This operator presents parallel composition of two processes (or behaviors). That is, a ∙ P1|| b ∙ P2 can choose to execute an initial transition a of P1 or an initial transition b of P2 in the interleaving manner, i.e., one after another. If the processes do not interact, ...

纯语法错误，scanf("%f%f%f",&a&b&c); 改成 scanf("%f%f%f",&a, &b, &c); 就可以了。

Describe the bug elm-review claims that a + b /= 0 is invalid but the Elm compiler and elm-test don't have an issue with it. By wrapping the math in parens, like (a + b) /= 0, then it parses fine in elm-review. This also applies to a + b...
