It can optionally contain embedded format tags that are replaced by the values specified in subsequent additional arguments and formatted as requested. Left-justify within the given field width; Right justification is the default see width sub-specifier. By default, only negative numbers are preceded with a -ve sign. Used with o, x or X specifiers the value is preceded with 0, 0x or 0X respectively for values different than zero.

Used with e, E and f, it forces the written output to contain a decimal point even if no digits would follow. By default, if no digits follow, no decimal point is written. Used with g or G the result is the same as with e or E but trailing zeros are not removed. Left-pads the number with zeroes 0 instead of spaces, where padding is specified see width sub-specifier. Minimum number of characters to be printed. If the value to be printed is shorter than this number, the result is padded with blank spaces.

The value is not truncated even if the result is larger. The width is not specified in the format string, but as an additional integer value argument preceding the argument that has to be formatted. If the value to be written is shorter than this number, the result is padded with leading zeros. The value is not truncated even if the result is longer. A precision of 0 means that no character is written for the value 0. By default all characters are printed until the ending null character is encountered.

When no precision is specified, the default is 1. If the period is specified without an explicit value for precision, 0 is assumed. The precision is not specified in the format string, but as an additional integer value argument preceding the argument that has to be formatted.

The argument is interpreted as a short int or unsigned short int only applies to integer specifiers: i, d, o, u, x and X. The argument is interpreted as a long int or unsigned long int for integer specifiers i, d, o, u, x and Xand as a wide character or wide character string for specifiers c and s. The argument is interpreted as a long double only applies to floating point specifiers: e, E, f, g and G.

If successful, the total number of characters written is returned.

You can use a string and memset function to fill it with any byte. Then you change the first and last bytes. Do a man memset for more info. Find More Posts by sarin View Blog.

Small example. Let's say that you've got the number of blank spces to print in 'numberofblanks': Code:. Or, without the for loop Find More Posts by Malicious.

That 'for' loop you displayed is exactly what I had in mind for implementing this. Sorry Malicious I will type 'man printf' and 'man memset' a little later to check this stuff out.

Introducing Spaces into printf statements C language?

Started by altair05Feb 06 AM. Please log in to reply. Posted 06 February - AM I would like to put in spaces in my print statements so that there are spaces when it runs. It's hard to explain so I'll try my best. How can I do that with multiple characters, for example replace 'g' with QTY. Edited by altair05, 06 February - AM. Posted 06 February - AM Yes, there is a way. As it's homework, I can't tell you the answer.The puts function is but one of many functions in the C programming language that sends text to the standard output device.

A second, more popular and versatile function is printf. It too displays information to the standard output device, but with a few more bells and whistles. On the surface, the printf function looks and works a lot like putsdisplaying text to the screen. Exercise 1: Eagerly create a new project in Code::Blocks, named ex Type the source code for main. If you can spot it, great job.

Exercise 2 : Create a new project, ex Use the printf function to create the same output as found in the listing Displaying Two Lines of Text. Use the full nursery rhyme:. The printf function sends a formatted stream of text to the standard output device. The official format is a bit overwhelming:. The name printf means print f ormatted, and the function really shows its horsepower in displaying formatted output.

The print part of the name hails back to the days when C programs sent their output primarily to printers, not to video displays.

After displaying the text, the cursor waits at the space after the d in world. The program runs, and it does exactly what you direct the computer to do, albeit without knowing how printf works ahead of time. To make the printf function display text on a line by itself, insert the newline character into the text string. You can type the newline character only by using a C language escape sequence. To reference certain characters that you cannot type into your source code, the C language uses something called an escape sequence.

The standard escape sequence uses the backslash character followed by a second character or symbol; for example:.

I try everything but cant find. In the C language, all characters exist as small integers usually 1 byte large. It never makes any sense to store characters in variables used for floating point calculation. EDIT : if the output of space should depend on the values of the doubles, then you should do like this:. And if you have absolutely no idea what the above means or why I did it, you probably shouldn't be doing floating any point programming, not before reading this.

Why would anyone ever want to do this? And what if the character you are trying to print isn't representable as an exact number in the particular floating point format?

You would be printing a different character. Lundin You are correct. Here OP want to print space character with double value d. I believe OP want to print only space characters,some double values and no other character. Gangadhar after my if block ends, my printf fonc. Because program reads some lines from text file and after calculating something prints. Declare d as char. The C language allows for more than 3 variables to co-exist in the same program Instead, built up an output format string in the desired format.
