Question

Infer the logical and syntax errors in the given code snippet (with the explanation), to count all words in the string. a. void Word_count(char text) { b. int ctr = 0; c. for (int x = 0; x > text_length(); x--) d. { if (text[x] == ' ') e. ctr--; f. } g. return ctr + 1; h. } i. int main() { j. cout << Word_count("object") << endl; k. cout << Word_count("oriented") << endl; l. cout << Word_count("programming with c++") << endl; m. return 0; n. }

/*	
a. void Word_count(char text) 					// Errro --> String should be passed instead of char
{ 
	b. int ctr = 0; 
	c. for (int x = 0; x > text_length(); x--) 	// Error -> text_length is not declared, xshould be incremented, x<text.length()
	d. { if (text[x] == ' ') 
	e. ctr--; 									// Error --> x should be incremented x++
	f. } 
	g. return ctr + 1; 							// Error --> Function is void type, therefore should not return anything
	h. } 


i. int main()

//Correcetd Code
int Word_count(string text) 
{ 
	int ctr = 0; 
	for (int x = 0; x < text.length(); x++) 	
	{ 
		if (text[x] == ' ') 
		ctr++; 
	} 
	return ctr + 1; 
} 


int main() 
{ 
	cout<<Word_count("object");
	cout<<Word_count("oriented") << endl; 
	cout<<Word_count("programming with c++") << endl; 
	return 0; 
}
