Memory Management

-


Total memory allocation of a Program are divided into 4 parts
  1.  Instruction
  2. Data
  3. Stack
  4.  Heap
what they store ?
  • Instruction  --- store all lines and instruction in program .
  • Data --   global and static variable.
  • Stack--  function , local , variable, variable in  function ,recursion time memory
                          and loop (any memory that are needed for operation)
                          time and various memory that are required at time while performing job .
  • Heap -- dynamic created memory.(by malloc , new ) 
  1. Instruction  and Data

    both memory size are fix at the time of program start .
2. Stack and Heap
 
  memory consumption change throughout the program.

What is Memory Leak? Discuss the importance.

What is Memory Leak? First we have to understand memory management. Memory leak occurs when programmers create a memory in heap and forget to delete it. Memory leaks are particularly serious issues for programs like daemons and servers  Memory leakage occurs in C++ when programmers allocates memory by using new keyword and forgets to deallocate the memory by using delete() function or delete[] operator. One of the most memory leakage occurs in C++ by using wrong delete operator. The delete operator should be used to free a single allocated memory space, whereas the delete [] operator should be used to free an array of data values. In c /* Function with memory leak */ #include <stdlib.h> void f () { int *ptr = ( int *) malloc ( sizeof ( int )); /* Do some work */ return ; /* Return without freeing ptr*/ }  In c++ // Program with memory leak #include <bits/stdc++.h> using ...

How bad is the Windows command line really?

If you have never had to interact with the Windows Batch language, this might not seem like such a big deal. Surely Batch could not be substantially worse than Bash, right? Bash: a language that was neither designed, nor evolved. An adequate solution to a problem that has since become orders of magnitude harder. As arcane as it is useful, as dangerous as it is ubiquitous, Bash: the language that asks how much we are willing to give up for convenience’s sake? Sure, Bash could be worse. But  substantially  worse? Bash had one value proposition: it was  just good enough . It is difficult to imagine that it would have flourished as it has, if that had that not been true. But the truth is what it is. Batch  is  substantially worse. And how much worse sort of beggars belief. Look: The time a batch script takes to execute is at least O(n*(n-1)/2) (aka O(n^2)) in the LENGTH OF THE FILE, INCLUDING COMMENTS. The reason is that the batch engine reads the entire f...

How to Take a Screen Shot Or Capture Computer Screen

Take a screenshot on Windows Look for the  Print Screen  key on your keyboard, which might be labeled  PrtScn  or some similar variation. To capture the entire screen (everything you see on the screen, including all open windows), press the  PrtScn  button. This screenshot will be placed in your clipboard. Alternatively, to capture just the active or foremost window, press  Alt + PrtScn . (Some machines may require you to tap  Fn  at the same time.) If you want to select a portion of your screen to grab, hit  Windows+Shift+S . In Windows 10, this will open the Snipping Tool, which we’ll explain below. Next, open a word processing or image editing program like Microsoft Paint and either go to  Edit > Paste  or hit  Ctrl + V  to paste the image into the program. Go to  File  >  Save As  and save the image to a folder so you can use it later.
