Description
In the following program “/ ***** N ***** /” There is an error in the next line of , Please correct （ Be careful ： No extra bank is allowed 、 Line reduction 、 Add sentence 、 Subtract , Otherwise, we will be responsible for the consequences ）. The program function ： Use recursion to convert a six digit integer n Convert to string , For example, the input 123456, Expected output string "123456". #include void itoa(long i,char s) { if(i==0) return; /***** 1 */ s = ‘1’+i%10; itoa(i/10,s-1); } void main() { long n; char str[7]=""; scanf("%ld",&n); / 2 ******/ itoa(n,str+6); printf("%s",str); }
Input
Enter a six digit positive integer n.
Output
Convert the integer to the corresponding string .
Sample Input`
123456
Sample Output
123456

#include <stdio.h>
void itoa(long i,char *s);
int main()
{
    
	long n;
	scanf("%ld",&n);
	char s[7] = " ";
	itoa(n,s+5);
	printf("%s\n",s);
	return 0;
}

void itoa(long i,char *s)
{
    
	if (i == 0)
		return;
	else 
	{
    
		*s = '0' + i%10;
		itoa(i/10,s-1);
		
	}
}

That's interesting , There are many mistakes
