Application:
AlstraSoft E-Friends
Scenario:
Suppose you are developing an online first-degree friendship building social network for
E-friends
application at Alstrasoft Pvt Ltd that strive to be the premier provider of webbased

While working in same programming environment you came across following piece of
code implemented in
C++.from the following code infer if it is following the principle of orthogonality or not? If NOT then explain with solid reason.
[5]
#include <iostream.h>
#include <stdio.h>
# include <conio.h>
using namespace std;
int main() {
char a[80];
char b[80]; int i, j;
cout << "Enter a sentence: ";
gets(a); // Read a token at a time from the string.
for(i=0;; i++) { /* Read characters until either a space or the null
terminator is encountered. */
for(j=0; a[i]!=' ' && a[i]; j++, i++)
b[j] = a[i];
b[j] = '\0'; // null terminate the token
b[j] = '\0'; // null terminate the token
cout << b << '\n';
if(!a[i])
break;
}
getch();
return 0;
}
