character is special as a single character; for example: printf(“Song, \”Under the Sea.\”\n”); The \” escape sequence is used to place a double-quote character in the middle of a string. Similarly, if you want to use a single quote character, you specify it as ‘\’’ That’s the \’ escape sequence inside single quotes. This modification to the SPONSOR.C program demonstrates: #include int main() { printf(“This program is sponsored by the letter %c%c%c\n”,’\’’,’P’,’\’’); return(0); }

exactly that kind of drudgery that the computer really doesn’t mind. When it comes to loops, your computer not only is an expert, but it also truly enjoys repeating itself. The core of most modern programs is the loop. It gives a program the ability to repeat a group of statements over and over, sometimes for a given count or duration, or, often, until a certain condition is being met. The C language gives you many ways to create loops in your code. The one presented in this chapter is the for

division — in order, from left to right: 60 divided by 6 is 10. Finally, 10 divided by 2 is 5. The official order of precedence is multiplication first and then division, addition, and, finally, subtraction, in order from left to right. Fooling old Sally with parentheses You can, and sometimes have to, override the order of precedence. For example, if you’re trying to calculate triple profits, you would want to use a program like this: #include int main() { int profits,profits3; int

explain it. Either that, or I just have so much to explain that it’s impossible to describe all that printf() can do in one chunk. This chapter is primarily about how printf() can format output. Part of that format involves printf() displaying information in non-base 10 numbering systems. Because of that, this chapter also covers those non-base 10 number systems, for your fun, frolic, and amusement. Going Numb with Numbering Systems Long before humans could write, they could count.
