问题 This may be a duplicate and I apologies if that is so but I really want a definitive answer as that seems to change depending upon where I look. Is it acceptable to say that a gigabyte is 1024 megabytes or should it be said that it is 1000 megabytes? I am taking computer science at GCSE and a typical exam question could be how many bytes in a kilobyte and I believe the exam board, AQA, has the answer for such a question as 1024 not 1000. How is this? Are both correct? Which one should I go

问题 Im trying to read a byte file with fstream in c++ (goal: binary data format deserialization). The dat file looks something like below in HxD Hex editor (bytes.dat): but something goes wrong when reading the binary file into a char array.. here is a mwe: #include <iostream> #include <fstream> using namespace std; int main (){ ofstream outfile; outfile.open("bytes.dat", std::ios::binary); outfile << hex << (char) 0x77 << (char) 0x77 << (char) 0x77 << (char) 0x07 \ << (char) 0x9C << (char) 0x04

问题 I am new to C programming and unsure what is wrong with my program. I am writing a program which takes an integer as an input and returns it in binary form. An input of 43 would output 101011, but the output is 1. Please advise. #include <stdio.h> #include <string.h> void printBinaryForm( int X ) //Purpose: Print parameter X in binary form //Output: Binary representation of X directly printed //Assumption: X is non-negative (i.e. >= 0) { //[TODO] CHANGE this to your solution. int input = X;

问题 I need to convert a binary input into a decimal integer. I know how to go from a decimal to a binary: n = int(raw_input('enter a number: ')) print '{0:b}'.format(n) I need to go in the reverse direction. My professor said that when he checks our code, he is going to input 11001 , and he should get 25 back. I've looked through our notes, and I cannot figure out how to do this. Google and other internet resources haven't been much help either. The biggest problem is that we are not allowed to
