Note that your question should be "Why isn't the output from printf() appearing when expected?" since you've not produced any evidence that the calls are not made but only that you don't see the output you expect.

If the program does not recognize stdin/stdout as an "interactive device", it will be fully buffered. In this case, output may be buffered until a call to fflush(stdout) (or one of a number of other function calls) is encountered.

Is the problem that scanf is not returning, or that the final call to printf is not producing output?
