About Us

"This page may not have the largest collection of concepts but its trying to explain some concepts in a best way."

 When we do not understand something or may not resolve something, we try to search it on the Internet but there are so many explanations, so many forums that it's hard to catch every explanation. So here, on this page, we have tried to explain the best scenario in which an article can be understood.

Typically, this page aims to cover the areas of C programming, System Programming and few other stuff. And yes, do visit the Portfolio page to read about tech biographies and experiences of programming practices or a project.

Please give suggestions if you feel so or if you find any errors. I would appreciate your participation.

Also ,if you want to share or ask anything ,just drop the contents of your topic to systemgenes@gmail.com.

error: stray '\' in program

 stray.c:6: error: stray '\315' in program   stray.c:7: error: stray '\242' in program   stray.c:8: error: stray '\234' in program  If you are getting error messages like above in your C/C++ program, then don't worry. ;-) Perhaps you have copied the code from somewhere. If your code is small ,then the simplest solution is that you should start typing it from zero. That is , delete all the code ( the lines you know you have copied) and re-type it. If your code is lengthy and you do not want to type it, then you should use this software : Hex Editor Wiki You may be wondering that why this problem even occurred. The reason for this is that your code might contain some hidden octal (not-readable) characters which the compiler cant understand and you can not see. They are present in your code because you have perhaps copied it from somewhere. So, simply you can retype the same code to solve the problem. ----- Happy Coding :-)

error: invalid application of ‘sizeof’ to incomplete type ‘struct ’

list.c:47:39: error: invalid application of ‘sizeof’ to incomplete type ‘struct Litsnode’ So, I was trying to run a program based on linked list and this is what I got. This is a very silly problem. I am mentioning it here just to help those who got frustrated like me :-\ Let me show you the line where this error occurred : 46   struct Listnode * newnode; 47   newnode = (struct Listnode *) malloc(sizeof(struct Litsnode)); Now, View it properly. Check the name(spelling) of the structure mentioned to sizeof : " struct Li ts node ". Though the defined name of the structure was : " struct Listnode " That's it.  This happens all the time that we may type something wrong. The important thing is to identify it. :-) Feel free to give any suggestions :)

Expandable Arrays in C : behind the code

Image
Arrays. They are beautiful. In C, we always try to work through restrictions arrays have i.e the size of the array must be statically defined. We always want a dynamic array whose size can be decided at run-time. There are ways which we use widely for e.g by using pointers and then dynamically allocating memory to it using malloc or calloc. But depending on the situation, we might require more efficient and organizable ways. I will explain the concept with a series of examples as in how simple arrays evolved to the tricky expandable ones. The classic way is to use pointers This snippet will allocate a memory block of size = array_size(integer array). Though this is not what I wanted to explain because this way is too clumsy. Imagine if you need 10 dynamic arrays in your program, you have to write these four lines each time and you have to keep track of all the 10 sizes. A better way is to use structures: We can simply create a structure containing two elements: array_size and...
