Nov 6, 2012 · The best you can do is use up one whole byte but ignore 5 of its bits. To do that (assuming that the number is always going to fit into a byte), convert the input string to an integral type: long l = strtol(c, 0, 2); Then get its least significant byte: unsigned char b = l & 0xffl; And write it to the file: fwrite(&b, 1, 1, binFile);
A byte is the smallest unit of storage that can be used in a first-class manner. On nearly all computers, a byte consists of 8 bits. There are a few peculiar computers (mostly “embedded controllers” for very small systems) where a byte is longer than that, but this manual does not try to explain the peculiarity of those computers; we assume that a byte is 8 bits.
Jul 23, 2019 · Clearly, using only 32 bits, it's not possible to store every digit in such numbers. When it comes to the representation, you can see all normal floating-point numbers as a value in the range 1.0 to (almost) 2.0, scaled with a power of two. So: 1.0 is simply 1.0 * 2^0, 2.0 is 1.0 * 2^1, and. -5.0 is -1.25 * 2^2.

Computer Memory is the hardware part of the system that stores data, information, and instructions. It is a device where data is stored, data is processed and instructions required for data processing are also stored. Computer memory stores both types of data that is, input and output.
Semiconductor memories.Faster than secondary memories.A computer cannot run without primary memory.It is the working memory of the computer.A computer processor is made up of multiple decisive circuits, each one of which may be either OFF or ON. These two states in terms of memory are represented by a 0 or 1. To count higher than 1, such bits (Binary Digits) are suspended together. A group of eight bits is known as a Byte. 1 Byte can represent numbers between zero (00000000) and 255 (1...
File transfer speedor data transfer speedrefers to the speed at which data is transmitted from one source to another. Typically measured in bits or bytes per second. Some of the file transfer speeds are: 1. Bits per Second(bps): It is the smallest unit of data transfer speedor file transfer speed. 2. Bytes per Second(Bps): 1Bps = 8bps. 1 byte=8 bit...
In conclusion, understanding computer memory is crucial for anyone navigating the digital landscape, whether you’re a seasoned professional or just starting out. From the intricacies of volatile and non-volatile memory to the evolution of storage units like kilobytes, megabytes, and beyond, this comprehensive guide has shed light on the fundamental...
Mar 1, 2021 · fseek and read function to read file streams to memory. Now we have to use some low-level language like C: # declare file pointer. File *fp; # initialize file pointer with a binary file stored on disk. fp = fopen('./test_file.bin','r'); # set the reading pointer from starting point (SEEK_SET) to 4 bits forward (offset = 4) fseek(fp,4,SEEK_SET ...
