(programming c-string)

Specifically you are not allowed to include string, cstdlib or math libraries. Also you are not allowed to use any built-in functions of c-strings.

bool isSubstring(const char *s1, const char* s2)

{

/* returns true is s1 is a substring of s2 otherwise returns false Definition: s1 is a substring of s2 if s1 is found in s2. That is all characters of s1 are found TOGETHER in s2 in the SAME ORDER as they appear in s1 Example "set" is a substring of "massachussettes" But "ets" is not substring of "massachussettes" */

}

int countWords(const char* s)

{

/* Given a c-string that contains some words separated by spaces, return the number of words in the c-string.

}

//Test isSubstring function

cout << endl; flag = isSubstring(s1, s4);

if (flag)

cout << s1 << " is a substring of " << s4 << endl;

else

cout << s1 << " is not a substring of " << s4 << endl; char s5[] = "abort";

char s6[] = "abcabodefaborhuhabortabunny";

flag = isSubstring(s5, s6);

if (flag)

cout << s5 << " is a substring of " << s6 << endl;

else

cout << s5 << " is not a substring of " << s6 << endl;

//Test countWords function

cout << endl;

char s7[] = "";

c = countWords(s7);

cout << "There are " << c << " words in " << s7 << endl;

char s8[] = "Test";

c = countWords(s8);

cout << "There are " << c << " words in " << s8 << endl;

char s9[] = "Nice one";

c = countWords(s9);

cout << "There are " << c << " words in " << s9 << endl;

char s10[] = "This is a nice assignment and hopefully an interesting as well";

c = countWords(s10);

cout << "There are " << c << " words in " << s10 << endl;

the ideal output is:

massachussettes is not a substring of htsemsaesuatscs

abort is a substring of abcabodefaborhuhabortabunny

There are 0 words in

There are 1 words in Test

There are 2 words in Nice one

There are 11 words in This is a nice assignment and hopefully an interesting as well
