Arithmetic can be performed on pointers. However, in pointer arithmetic, a pointer is a valid operand only for the addition(+) and subtraction(-) operators. An integral value n may be added to or subtracted from a pointer ptr. Assuming that the data item that ptr points to lies within an...
这是由于试图让一个指针加上一个非整形的数，比如int* p; p+1.1 下面是MSDN里的解释：Error Message '+' : pointer addition requires integral operand An attempt was made to add a nonintegral value to a pointer using the plus ( + ) operator.The following sample generates C2111:Cop...

Certainaddition, subtraction,compound assignment,increment, and decrementoperators are defined for pointers to elements of arrays. Comparison operatorsare defined for pointers to objects in some situations: two pointers that represent the same address compare equal, two null pointer values compare equal, ...
Therefore it is not a valid operand to an addition operation. Therefore you cannot perform pointer arithmetic on a void pointer. Notes Originally, it was thought that void* arithmetic was permitted, because of these sections of the C standard: 6.2.5-27: A pointer to void shall have the ...
The C Standard Speaks Quotes are taken from the n1256 draft. The standard's description of the addition operation states: 6.5.6-2: For addition, either both operands shall have arithmetic type, or one operand shall be a pointer to an object type and the other shall have integer type. ...
