memset(a,1,sizeof(a))to initialize the array is not a desired effect, as will memset each byte value of 1 becomes 16,843,009. - sizeof during compilation is converted to the corresponding number (although hear a standard representation, in order to meet some dynamic array may be calculated at run time), so please do not use the function pointer type sizeof calculate the size parameter, it returns a pointer length, instead of the pointer address length (arrays, structures, classes).
- sizeof calculates the end of the string
\0, and strlen will not. - C storage location change may occur when the vector adding new elements, the entire vector is launching a mobile location.
