accounted for 10 bytes, to 4-byte alignment, so you need to complement two bytes, so two 0xcc, resulting in a 10 byte between the BF and array. The one next to the above array should be two 0xcc to complement the alignment. It was deliberately marked to the back. The purpose of this identification here is to illustrate the principle of checkstackvars this inspection. OK, clear the memory distribution, then checkstackvars at what time to perform the check, in C + + code can not be displayed to

locations are typically on the stack, but may also be in registers; this is specified by calling conventions. Program Execution jumps to the address of the called function. Inside the function, registers ESI, EDI, EBX, and EBP are saved on the stack. The part of code that performs these operations is calledFunction PROLOGAnd usually is generated by the compiler. The function-specific code is executed, and the return value is placed into the eax re

So I collected some useful modules on the Internet and integrated them to implement support. xp3, xp2 should be supported even if it is not tested.

are eax,ebx,ecx,edx,edi,esi. These registers can be used arbitrarily in most directives. However, some instructions restrict the use of some of these registers for some purpose, such as the Division directive IDIVL the dividend in the EAX register, the edx register must be 0, and the divisor can be any register. The quotient of the calculated result is stored in the EAX register (covering the divisor), and the remainder is stored in the edx register.

-dimensional space: (3) Euclidean distance between two n-dimensional vector A (x11,x12,..., x1n) and B (x21,x22,..., x2n): It can also be expressed in the form of a vector operation: (4) Matlab calculates Euclidean distance MATLAB calculates distances primarily using the Pdist function. If X is a matrix of MXN, then Pdist (x) takes each row of the X matrix M as an n-dimensional vector and calculates the distance between the M vectors 22. Example:
