Convert an unsigned integer into a string, using a given base
#include <stdlib.h>
char* utoa( unsigned int value,
char* buffer,
int radix );
- 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.

Use the -l c option to
qcc
to link against this library.
This library is usually included automatically.
The utoa() function converts the unsigned binary integer
value into the equivalent string in base radix
notation, storing the result in the character array pointed to by
buffer. A null character is appended to the result.
A pointer to the result.
#include <stdio.h>
#include <stdlib.h>
int main( void )
{
int base;
char buffer[18];
for( base = 2; base <= 16; base = base + 2 )
printf( "%2d %s\n", base,
utoa( (unsigned) 12765, buffer, base ) );
return EXIT_SUCCESS;
}
produces the output:
2 11000111011101
4 3013131
6 135033
