I've fixed most of the code now and cannot figure out how to loop my if statement if anyone could point me in where I should be looking.

int main() { //declare variables string sentence, word, acronym; string::size_type location; ifstream myIn;

myIn.open("../Acronym.dat"); //open file
assert(myIn); //check if file can be opened

//find white space & capitalize next word
while (getline(myIn,sentence))
{
    acronym = sentence.substr(0,1); //bring out first letter
    location =sentence.find(" ");
    //while
    {
    if (location == (sentence.find(" "))) //capitalize word
    {
        sentence[location+1]=toupper(sentence[location+1]);
        acronym+= sentence[location+1];
        location = sentence.find(" ");
        cout << acronym << endl;
    }
    }
}

myIn.close();
return 0;

}
