In late September and early October, I wrote a series of lessons on how the various printf()<\/em> formatting commands are used. Now it’s time to put your skills to the test.
\n
\nAs a review, the four lessons covered the following aspects of the printf()<\/em> function’s various conversion characters:<\/p>\n

Integer Output (September 21)<\/a><\/p>\n

Floating Point Output (September 28)<\/a><\/p>\n

Text Output (October 5)<\/a><\/p>\n

Other Output (October 12)<\/a><\/p>\n

Feel free to reference those Lessons, which may come in handy as you try to craft code to work this month’s exercise.<\/p>\n

To get you started, here is the program’s skeleton:<\/p>\n

\r\n#include <stdio.h>\r\n\r\nint main()\r\n{   \r\n    int age = 52;\r\n    double nd = 16750588107179.74;\r\n    char *name = \"Barack Obama\";\r\n\r\n\/* Output statements go here *\/\r\n\r\n    return(0);\r\n}<\/pre>\n
Your goal is to use various printf()<\/em> statements to generate output exactly like this:<\/p>\n
0000000000000052\r\n34\r\n16750588107180\r\n1.675e+13\r\n          Barack\r\nBarack  <\/code><\/pre>\n
Use the three variables listed in the skeleton as the basis for the output. You cannot modify the variable’s values. Instead, use the printf()<\/em> function’s conversion statements to generate the output.<\/p>\n
As I admonish every month, please attempt to solve the exercise on your own before you peek at my solution, shown below.<\/p>\n
Exercise Solution<\/a><\/p>\n
Note:<\/strong> Yes, I’m using President Obama’s name in this code. As I’ve done since I wrote my first programming book back in the 1990s, I used the current president’s name in my examples. I did so for Bill Clinton and George W. Bush. It is not a political statement; Mr. Obama is the President and his name is well-known and up for grabs.<\/p>\n
Oh, and 52 is his age and the nd<\/code> variable value is the current US national debt.<\/p>\n","protected":false},"excerpt":{"rendered":"
