In this code snippet what does the line (line 20) that reads
cause to the flow of the program, if anything? If it does nothing why would someone have it there?
mode = -1;
while ( /* read a line from a file */ )
// Do something for when mode < 0
else if (mode==0)
if ( /* some condition */ )
else if ( /* some other condition */ )
// Code for some other condition
else ; <<-- What does this do?
else // mode is 1
// A lot of code for mode 1
} // end mode=1 code
// Code after the while loop
