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...

Method 4: Decimal to Binary in C Programming with Bitwise Operator An operator known as a bitwise operation manipulates each of the bits of binary symbols that represent integers. The following is a basic C script that uses bitwise operations to translate a number in decimals into binary: ...
Mark Siegesmund, in Embedded C Programming, 2014 Binary Bitwise Operators Binary operators (or bitwise operators) are mathematical operators that view the data from a binary perspective. These operators are not permitted on float types. See Table 5.3. Table 5.3. Binary bitwise operator list. Left...

Writing the Binary File Using Insertion Operator (<<) Of fstream Library Similar to writing to the text file, you can write to the binary file using the insertion operator (<<). This operator is overloaded in the ostream class and inherited in the fstream class. You can use the insertion...
