When the lines of code that are in red are removed, the program works very quickly, but when it's kept, it works extremely slowly.Code:while(1) { c = fgetc(fo); if(c == EOF){ break; } else{ c = c + 'c' + 'd' - 't'; fputc(c,fw); cnt++; if(cnt % d == 0) { prog++; } printf(" %d%%\r", prog); fflush(stdout); } } printf(" %d%%\n", prog); printf("DONE!\n");
This is part of a program that encrypts characters from a file and then outputs it into another file. I created this progress meter to show how long it takes when encrypting. When the file size is small, < 5kb, there is no problem. But when it's 3MB, then it takes upto 5 minutes when the progress meter is there, when I remove it, it takes only 5 seconds.
I don't see what the problem with the code is.
