Been learning some very basic C++... My question concerns the following block of code:
Code:
//A program to count words in a sentence
#include <iostream>
#include <string>
std::string sentence;
int spaceCounter = 0;
int current;
int main()
{
std::cout << "Sentence: ";
std::cin >> sentence;
int lengthOf = sentence.length();
for(current = 0; current <= lengthOf; ++current)
{
if(sentence.at(current) == ' ')
++spaceCounter;
}
std::cout << spaceCounter + 1 << " words.\n";
return(0);
}
I expect this program to act like this:
Code:
$ ./spaceCounter
Sentence: a simple sentence
3 words.
Instead, it runs like this:
Code:
$ ./spaceCounter
Sentence: a simple sentence
Aborted
Can anyone either a) find the error or b) explain to me why it does not work?
