1.3 Write a value that outputs any type of double (can make negative numbers, only printdigit with I/O)

#include <iostream>using namespace std;void printint (int a) {if (a >=) printint (A/10);cout<< (a%10);} void Printreal (Double a) {while (! ( A > -0.0000001 && a < 0.000001)) {a *= 10;cout<< (int) a;a = A-int (a);}} void Test (Double a) {if (a < 0.0) {cout<< "-"; a =-A;} Printint (int) a);cout<< "."; Printreal (A-int (a)); int main () {//Your code goes Heretest ( -123.45); return 0;}
