M maharg idspispopd Jun 8, 2004 #2 Um... are you asking how to use scanf? Because scanf always reads from stdin.
7 7imz Member Jun 8, 2004 #3 no i mean.. if i give it a file, say text.txt... how can i read the contents of that file?
M maharg idspispopd Jun 8, 2004 #5 Run it like this: myprog < file.txt If you want your program to open the file, use fopen() to open it, then use fscanf instead of scanf.
