Apointeris a very powerful and sophisticated feature provided in the C language. A variable defined in a program the compiler allocates a space in thememoryto store its value. The number of bytes allocated to the variable depends on itstype.For instance, acharacteris allocated 1 byte, aninti...
In HTML, declarations are used to define the document type and other metadata. The <!DOCTYPE> declaration specifies the HTML version, while the tag is used for defining character encoding, viewport settings, and other information. Can I ...

Java 8 is a giant step forward for the Java language. Writing this book has forced me to learn a lot more about it. In Project Lambda, Java gets a new closure syntax, method-references, and default methods on interfaces. It manages to add many of the features of functional languages wit...
For example if the overwritten part in memory contains a pointer (an object that points to another place in memory) the attacker’s code could replace that code with another pointer that points to an exploit payload. This can transfer control of the whole program over to the attacker’s code...

a cursor and a mouse pointer are often used interchangeably, but they're not the same thing. a cursor is a more general term for any indicator used in a software interface. a mouse pointer, on the other hand, specifically refers to the arrow or hand symbol that you control with your ...
The real reason you would use this is if you needed to make a function call to a C library that requires a pointer. Let’s go back to the add_one() C-function from before: C void add_one(int *x) { *x += 1; } Here again, this code is incrementing the value of x by ...
Developers can also check the most significant bit of characters in a sequence to verify that a data stream, string or file contains ASCII values. The most significant bit of basic ASCII characters will always be 0; if that bit is 1, then the character is not an ASCII-encoded character. ...
Checking the integrity: Perform the checking before the program pointer becomes invalid. Randomizing the address space: Arrange the address space positions in the key data area randomly. Typically, buffer overflow attacks require the locations of executable code, which is almost impossible after the ...
