convert number to string c

// I know of three methods to do this.

//method 1: '#' is the preprocessor operator that converts to string. 
//It is called stringification or stringizing operator.
#define TO_STR(x) #x
char *s=TO_STR(123;
  
//method 2: sprintf()
char*s;
sprintf(s,"%d",123);

//method 3: itoa(), the third parameter is base, so to convert number to binary, put base as 2.
char*s;
itoa(123,s,10)

c convert integer to string

int numToConvert = *your number*;

 // calculate the length of the resulting string
int ENOUGH = malloc(sizeof(char)*(int)log10(numToConvert));
char str[ENOUGH];

sprintf(str, "%d", 42);

// str contains the number in string form

num to string in c

int num = 321;
char snum[5];

// convert num to string and save in string snum
itoa(num, snum, 10);

// print our string
printf("%s
", snum);

convert int to string c

char s[] = "42";
int num = atoi(s);
