Advanced Programming Midterm 2 Review exam with verified answers. stdin incoming character stream, normally from keyboard, line-buffered Practice questions for this set Terms in this set (62) stdout outgoing character stream, normally to terminal screen, buffered until newline comes or buffer is filled stderr outgoing character stream, normally to terminal screen, unbuffered Redirect stdin < Redirect stdout > Redirect stderr 2> Append >> Link stderr and stdout 2>&1 Pipeline connects stdout of one program to stdin of another program, prog1 < input_file | prog2 | prog3 > output_file == cat input_file | prog2 | prog3 > output_file scanf most conversions skip leading white space, takes variable number of parameters, stores formatted input in a variable printf takes variable number of arguments, prints formatted string to stdout sscanf read from a string rather than stdin sprintf write to output_buffer rather than stdout, make sure output_buffer is big enough, snprintf is a safer version EOF special value indicating end-of-file, usually defined to be -1, getchar() returns int to represent this fopen() opens a file, returns a pointer so it can be passed, 'r', 'w+' , 'rb', must pass mode for the file, returns NULL if file can't be opened
