Need help using pointers.

[besurk]

Could someone help me to determine what I am doing wrong in my program. I am trying to use pointers to count the numbers of words in a given string.

#include <iostream>
using namespace std;

int findWord(char *str, int size);

int main()
{
	char str[100];

	cout << "Enter a sentence: " << endl;
	cin >> str;
	
	int words = findWord(str, 99);

	cout << "There are " << words << " words in the sentence " << endl;

	return 0;
}
int findWord(char *str, int size)
{
	int count = 0;
	
	while (*str)
	{
		if (*str == ' ')
			count++;
	}
	return count;
}

What's doing?
Error messages?

The program is able to compile, but when I input a sentence, it just goes down the the next line. I think my error is within the function.

Your while loop is infinite because you never do anything that could make the condition false. Maybe you meant to increment the pointer?

seems like you don't really understand howwhile works

try this:

int findWord(char *str, int size)
{
	int count = 0;
	
	while (count < size)
	{
		if (condition_are_met)
			break;
		++count;
	}
	return count;
}
