Program Notes

Note that whereas the continue statement causes the program in Listing 6.12 to skip the rest of the loop body, it doesn’t skip the loop update expression. In a for loop, the continue statement makes the program skip directly to the update expression and then to the test expression. For a while loop, however, continue makes the program go directly to the test expression. So any update expression in a while loop body following the continue would be skipped. In some cases, that could be a problem.

This program doesn’t have to use continue. Instead, it could use this code:

if (line[i] == ' ')    spaces++;

However, the continue statement can make a program more readable when several statements follow the continue. That way, you don’t ...
