C General - Convert an integer or a float to a string

Convert an integer or a float to a string

Q

Does there exist any other function which can be used to convert an integer or a float to a string?

✍: FYIcenter

A

Some implementations provide a nonstandard function called itoa(), which converts an integer to string.

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.

Another 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 );

Bitwise Operations
Which bit wise operator is suitable for turning on a particular bit in a number? The bitwise OR operator. In the following code snippet, the bit number 24 is turned ON: enum { KBit1 = 0x00000001 KBit2 = 0x00000010, KBit3 = 0x00000100, ... }; some_int = some_int | KBit24; 2007-02-26, 6130👍, 0💬

malloc Function
Why does malloc(0) return valid memory address? What's the use? malloc(0) does not return a non-NULL under every implementation. An implementation is free to behave in a manner it finds suitable, if the allocation size requested is zero. The implmentation may choose any of the following actions: * A... 2007-02-26, 5999👍, 0💬

Pointer to Constants
What is the difference between const char* p and char const* p? In const char* p, the character pointed by "p" is constant, so you can not change the value of character pointed by p but u can make "p" refer to some other location. In char const* p, the pointer "p" is constant not the character refer... 2007-02-26, 5917👍, 0💬
