Returns the length of the C string str. The length of a C string is determined by the terminating null-character: A C string is as long as the number of characters between the beginning of the string and the terminating null character (without including the terminating null character itself). This should not be confused with the size of the array that holds the string. Mar 06, 2011 printf lives in cstdio. Std::cout lives in ostream. You must declare the functions by including appropriate headers.

Description
The C library function int printf(const char *format, ..) sends formatted output to stdout.
Declaration
Following is the declaration for printf() function.
Parameters
format − This is the string that contains the text to be written to stdout. It can optionally contain embedded format tags that are replaced by the values specified in subsequent additional arguments and formatted as requested. Format tags prototype is %[flags][width][.precision][length]specifier, which is explained below −
Sr.No. | Specifier & Output |
---|---|
1 | c Character |
2 | d or i Signed decimal integer |
3 | e Scientific notation (mantissa/exponent) using e character |
4 | E Scientific notation (mantissa/exponent) using E character |
5 | f Decimal floating point |
6 | g Uses the shorter of %e or %f |
7 | G Uses the shorter of %E or %f |
8 | o Signed octal |
9 | s String of characters |
10 | u Unsigned decimal integer |
11 | x Unsigned hexadecimal integer |
12 | X Unsigned hexadecimal integer (capital letters) |
13 | p Pointer address Interaction Mode: Hold. Assignment: Deck A(Note: Make sure whichever Deck you choose is set to the same deck as the Load Selected function)Lastly, in the Button Options section, click to the left of Invert to create a check mark in the box.By clicking Invert, we have reversed when the Sync On feature is activated. Traktor 2 pro download. The newly added ultra-low latency mode can be used for live performance or work Use of the room. In addition, the treble correction can be made more natural, and the interface and tools have been optimized to bring a more convenient production experience to users. Moreover, especially the new version brings a brand-new operating interface and has the characteristics of low latency. In addition, the software allows users to change and modify the pitch without changing any of the original performance sound quality. This can be perfectly compatible with 32-bit and 64-bit operating systems. |
14 | n Nothing printed |
15 | % Character |
Sr.No. | Flags & Description |
---|---|
1 | - Left-justify within the given field width; Right justification is the default (see width sub-specifier). |
2 | + Forces to precede the result with a plus or minus sign (+ or -) even for positive numbers. By default, only negative numbers are preceded with a -ve sign. |
3 | (space) If no sign is going to be written, a blank space is inserted before the value. |
4 | # 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. |
5 | 0 Left-pads the number with zeroes (0) instead of spaces, where padding is specified (see width sub-specifier). |
Sr.No. | Width & Description |
---|---|
1 | (number) 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. |
2 | * The width is not specified in the format string, but as an additional integer value argument preceding the argument that has to be formatted. |

Sr.No. | .precision & Description |
---|---|
1 | .number For integer specifiers (d, i, o, u, x, X) − precision specifies the minimum number of digits to be written. 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. For e, E and f specifiers − this is the number of digits to be printed after the decimal point. For g and G specifiers − This is the maximum number of significant digits to be printed. For s − this is the maximum number of characters to be printed. By default all characters are printed until the ending null character is encountered. For c type − it has no effect. When no precision is specified, the default is 1. If the period is specified without an explicit value for precision, 0 is assumed. |
2 | .* The precision is not specified in the format string, but as an additional integer value argument preceding the argument that has to be formatted. |

Sr.No. | Length & Description |
---|---|
1 | h The argument is interpreted as a short int or unsigned short int (only applies to integer specifiers: i, d, o, u, x and X). |
2 | l The argument is interpreted as a long int or unsigned long int for integer specifiers (i, d, o, u, x and X), and as a wide character or wide character string for specifiers c and s. |
3 | L The argument is interpreted as a long double (only applies to floating point specifiers: e, E, f, g and G). |
additional arguments − Depending on the format string, the function may expect a sequence of additional arguments, each containing one value to be inserted instead of each %-tag specified in the format parameter (if any). There should be the same number of these arguments as the number of %-tags that expect a value.
Return Value
If successful, the total number of characters written is returned. On failure, a negative number is returned.
Example
The following example shows the usage of printf() function.
Let us compile and run the above program to produce the following result −
