Question

struct Keyword
{
    std::string keyword;
    int numUses;
};  

bool sortingVector(const Keyword& key1, const Keyword& key2)
{
    return key1.numUses < key2

struct Keyword
{
    std::string keyword;
    int numUses;
};  

bool sortingVector(const Keyword& key1, const Keyword& key2)
{
    return key1.numUses < key2.numUses;
}

int main()
{
    std::vector topKeywords(100);

    // imagine topKeywords initialization here

    std::sort(topKeywords.begin(), topKeywords.end(), sortingVector);

    return 0;
}

Compiles fine on my machine (gcc version 4.4.3).
