  • class member access specifiers and binary code

    - by pdehaan
    I understand what the typical access specifiers are, and what they mean. 'public' members are accessible anywhere, 'private' members are accessible only by the same class and friends, etc. What I'm wondering is what, if anything, this equates to in lower-level terms. Are their any post-compilation functional differences between these beyond the high-level restrictions (what can access what) imposed by the language (c++ in this case) they're used in. Another way to put it - if this were a perfect world where programmers always made good choices (like not accessing members that may change later and using only well defined members that should stay the same between implementations), would their be any reason to use these things?

  • binary number comparison

    - by EquinoX
    If I have a 32 bit two's complement number and I want to know what is the easiest way to know of two numbers are equal... what would be the fastest bitwise operator to know this? I know xor'ing both numbers and check if the results are zero works well... any other one's? how about if a number is greater than 0?? I can check the 31'st bit to see if it's greater or equal to 0..but how about bgtz?

  • Pointers in C with binary file

    - by darkie15
    Hi All, I am reading the contents of the file using fread into an char array. But I am not sure why it is not getting printed in the output. Here is the code: void getInfo(FILE* inputFile) { char chunk[4]; int liIndex; for (liIndex = 0 ; liIndex < 4 ; liIndex++) { fread(chunk, sizeof(char), 4, inputFile); } printf("\n chunk %s", chunk); } Output prints nothing at all. Where am I going wrong? Regards , darkie

  • Float to binary in C++

    - by Eric
    Hi, I'm wondering if there is a way to represent a float using a char in C++? For example: int main() { float test = 4.7567; char result = charRepresentation(test); return 0; } I read that probably using bitset I can do it but I'm not pretty sure.

  • Venture Capital SEO (Search Engine Optimization)

    Back in the day, venture capitalists relied on tips, networking and brute force to find companies to invest in.

A quick resource for start-up companies looking for companies to invest in them, today's venture capitalists have been forced to change the way they do business - now they must spend more of their time advertising.

    - by restrictedinfinity
    Typically in a the input file is capable of being partially read and processed by Mapper function (as in text files). Is there anything that can be done to handle binaries (say images, serialized objects) which would require all the blocks to be on same host, before the processing can start.

The main reason for this is that the people at Google are constantly ahead of the game. At any given time all that anyone has to work with is a snapshot of what the Google team was doing a number of months ago.
