Strcmp in C/C strcmp is a built-in library function and is declared in header file. This function takes two strings as arguments and compare these two strings lexicographically. Mar 19, 2013 If your course uses Turbo C and you are simply wishing to use another compiler at home then your only option is to copy the libraries from the install of Turbo C and move them to the default location of the libraries used by Dev C. Conio.h is a C (programming language) C header file used in old MS-DOS compilers to create text user interfaces. It is not described in The C Programming Language (book) The C Programming Language book, and it is not part of the C standard library, ISO C nor is it required by POSIX. This header declares several useful library functions for performing 'console input and output' from a program. Jan 18, 2003 DevC accepts neither 'conio.h' nor 'conio.c' Hi. Undefined reference to `cprintf' When using conio.c: #2. View Profile. It is a Borland extension, and works only with Borland compilers (and perhaps some other commercial compilers). Dev-C uses GCC, the GNU Compiler Collection, as it's compiler. GCC is originally a. Composes a string with the same text that would be printed if format was used on printf, but instead of being printed, the content is stored as a C string in the buffer pointed by str. The size of the buffer should be large enough to contain the entire resulting string (see snprintf for a safer version). A terminating null character is automatically appended after the content.

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 |
| 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.

Let us compile and run the above program to produce the following result −
conio.h is a C (programming language) C header file used in old MS-DOS compilers to create text user interfaces. It is not described in The C Programming Language (book) The C Programming Language book, and it is not part of the C standard library, ISO C nor is it required by POSIX.
This header declares several useful library functions for performing 'console input and output' from a program. Most C compilers that target DOS, Windows 3.x, Phar Lap (company) Phar Lap, DOSX, OS/2, or Win32[1] have this header and supply the associated library functions in the default C library. Most C compilers that target UNIX and Linux do not have this header and do not supply the library functions. Some embedded systems are using a conio-compatible library [2].
The library functions declared by conio.h vary somewhat from compiler to compiler. As originally implemented in Lattice C, the various functions mapped directly to the first few DOS int 21h functions. But the library supplied with Borland's Turbo C did not use the DOS API but instead accessed video RAM directly for output and used BIOS interrupt calls; they also have additional functions inspired on the successful Turbo Pascal library.
Compilers that targeted non-DOS operating systems, such as Linux[citation needed], Win32 and OS/2, provided different implementations of these functions.[citation needed] The version done by DJ Delorie for the DJGPP GO32 extender is particularly extensive[3]. Another example is SyncTERM#Libraries SyncTERM's ciolib.

Compilers provided later than 1989 have prepended an _ to the names, to comply with the requisites of the ANSI C Standard.
