The problem is that when I starts typing the first char I type gets doubled on…

Guarantee uint8_t smaller then value

I would like to guarantee that a unsigned value is smaller then a threshold without a branch and without the modulo operator(requirement): The algorithm with modulo: x = x % threshold; The algorithm with a loop/branch: while(x >= m) { x -= m; } In special cases (like threshold == 8), this can be achieved by: x = x &…

Each thread one-by-one sequentially, reads one character per file (different file) and stores into the global constant. Example thread 1 reads character ‘a’ from file1, then wait for thread 2 & 3 to the same (i.e. read…
