Use thereadFunction to Read Binary File in C Alternatively, we can use thereadfunction that is essentially a system call underneath the hood. Notice thatreadworks on file descriptors; thus the file should be opened with theopensystem call. It takes additional two arguments denoting thevoidpointer ...
In addition to the commonly used fprintf and dprintf functions for directing output to the stderr stream in C, the fwrite function provides an alternative approach. While fwrite is traditionally used for binary stream I/O, it can be effectively utilized for text output, offering a unique perspec...
//create and open the binary file fp =fopen("aticleworld.dat","wb"); if(fp ==NULL) { printf("Error in creating the file\n"); exit(1); } //Get the length of message length =strlen(message); //write the message len in file ...

Testing a bit of a number is important in circuits when you need to read a value from a variable. For example, you may have a microcontroller connected to a keypad. Each key of the keypad represents a different binary number because each has its own code. In order to know which key is...
Create a set of C APIs to invoke the C++ APIs from Dynamsoft Barcode Reader v10.0. Compile these APIs into a shim DLL that acts as a compatibility layer, facilitating the linkage between the MSVC-built DLLs and MinGW GCC.

That is, when you write a C program and want to run it, you must compile the source code that you wrote into a binary low-level form that the computer understands. You can compare this to the scripting languages that we’ll discuss later, where you don’t need to compile anything. C...
