Trouble with formatting titles :( Your friend is in charge of recording titles of books in...

Program:

#include <iostream>
using namespace std;

/**
* REQUIRES: str must contain all lowercase letters
* MODIFIES: nothing
* EFFECTS: Returns a string identical to str formatted in
* Title Case
*/
string stringToTitleCase(string str) {
// Implement this function
string tmp = str;
tmp[0] = toupper(tmp[0]);
for(int i=1; i<tmp.size(); i++)
{
if(tmp[i-1]==' ' && tmp[i]!=' ')
tmp[i] = toupper(tmp[i]);
}
return tmp;
}

int main() {
cout << stringToTitleCase("hello") << endl;
cout << stringToTitleCase("look! i'm a title!") << endl;
}
