itoa()
Convert an integer into a string, using a given base
Synopsis:
#include <stdlib.h> char* itoa( int value, char* buffer, int radix );
Since:
BlackBerry 10.0.0
Arguments:
- value
- The value to convert into a string.
- buffer
- A buffer in which the function stores the string.
The size of the buffer must be at least:
8 × sizeof( int ) + 1
bytes when converting values in base 2 (binary).
- radix
- The base to use when converting the number.
If the value of radix is 10, and value is negative, then a minus sign is prepended to the result.
Library:
libc
Use the -l c option to qcc to link against this library. This library is usually included automatically.
Description:
The itoa() function converts the integer value into the equivalent string in base radix notation, storing the result in the specified buffer. The function terminates the string with a NUL character.
Returns:
A pointer to the resulting string.
Examples:
#include <stdio.h> #include <stdlib.h> int main( void ) { char buffer[20]; int base; for( base = 2; base <= 16; base += 2 ) { printf( "%2d %s\n", base, itoa( 12765, buffer, base ) ); } return EXIT_SUCCESS; }
produces the output:
2 11000111011101 4 3013131 6 135033 8 30735 10 12765 12 7479 14 491b 16 31dd
