For a positive integer with no more than 5 digits, the requirements: 1. Find out how many digits it is; 2. Output each digit separately ------

#include <stdio.h> 
#include <string.h> 
int main() 
{ 
	int i,a,cd; 
	char num[]={0};  
	char num1[]={0}; 
	//put into the array Input data 
	  scanf ("%s",num); 
   //Using the string length detection function to measure the length 
	  cd=strlen (num); 
	  printf ("It is a %d digit\n",cd);       
	  //Using FOR loop to output the array value, here do not directly use the Printf function to output the array value, otherwise it will affect the result 
	for (i=0;i<cd;i++) 
	{ 
		printf ("%c ",num[i]); 
	} 
		printf ("\n"); 
		//Use the FOR loop to exchange array values, and then use the FOR loop to output. 
	for (i=0,a=cd-1;i<cd;i++,a--) 
	{ 
		num1[a]=num[i]; 
	} 
	for (i=0;i<cd;i++) 
	{ 
		printf ("%c",num1[i]);
	}
		
	printf ("\n");



	return 0;
}
