Does there exist any other function which can be used to convert
an integer or a float to a string?
Some implementations provide a nonstandard function called itoa(), which converts
an integer to string.
#include
char *itoa(int value, char *string, int radix);
DESCRIPTION
The itoa() function constructs a string representation of an integer.
PARAMETERS
value:
Is the integer to be converted to string representation.
string:
Points to the buffer that is to hold resulting string.
The resulting string may be as long as seventeen bytes.
radix:
Is the base of the number; must be in the range 2 - 36.
A portable solution exists. One can use sprintf():
char s[SOME_CONST];
int i = 10;
float f = 10.20;
sprintf ( s, “%d %f\n”, i, f );
