  2. Return statement - Wikipedia

    en.wikipedia.org/wiki/Return_statement

    The return address is saved by the calling routine, today usually on the process's call stack or in a register. Return statements in many programming languages allow a function to specify a return value to be passed back to the code that called the function.

  3. Call stack - Wikipedia

    en.wikipedia.org/wiki/Call_stack

    In a language with free pointers or non-checked array writes (such as in C), the mixing of control flow data which affects the execution of code (the return addresses or the saved frame pointers) and simple program data (parameters or return values) in a call stack is a security risk, and is possibly exploitable through stack buffer overflows ...

  4. Java syntax - Wikipedia

    en.wikipedia.org/wiki/Java_syntax

    The syntax of Java is the set of rules defining how a Java program is written and interpreted. The syntax is mostly derived from C and C++. Unlike C++, Java has no global functions or variables, but has data members which are also regarded as global variables. All code belongs to classes and all values are objects.

  5. Calling convention - Wikipedia

    en.wikipedia.org/wiki/Calling_convention

    However, such subroutines do not need to return that value to r14—they merely need to load that value into r15, the program counter, to return. The ARM calling convention mandates using a full-descending stack. In addition, the stack pointer must always be 4-byte aligned, and must always be 8-byte aligned at a function call with a public ...

  6. Data segment - Wikipedia

    en.wikipedia.org/wiki/Data_segment

    The stack segment contains the call stack, a LIFO structure, typically located in the higher parts of memory. A "stack pointer" register tracks the top of the stack; it is adjusted each time a value is "pushed" onto the stack. The set of values pushed for one function call is termed a "stack frame". A stack frame consists at minimum of a return ...

  7. Stack (abstract data type) - Wikipedia

    en.wikipedia.org/wiki/Stack_(abstract_data_type)

    Several algorithms use a stack (separate from the usual function call stack of most programming languages) as the principal data structure with which they organize their information. These include: Graham scan, an algorithm for the convex hull of a two-dimensional system of points. A convex hull of a subset of the input is maintained in a stack ...

  8. Function (computer programming) - Wikipedia

    en.wikipedia.org/.../Function_(computer_programming)

    Assign a data type to the return value, if any; Specify a return value in the function body; Call a function; Provide actual parameters that correspond to a called function's formal parameters; Return control to the caller at the point of call; Consume the return value in the caller; Dispose of the values returned by a call

  9. Stack trace - Wikipedia

    en.wikipedia.org/wiki/Stack_trace

    In computing, a stack trace (also called stack backtrace [1] or stack traceback [2]) is a report of the active stack frames at a certain point in time during the execution of a program. When a program is run, memory is often dynamically allocated in two places: the stack and the heap. Memory is continuously allocated on a stack but not on a ...
