示例1: eliminateDuplicates
//Eliminates duplicates from the global vars
void eliminateDuplicates(strvec& vecRef)
{
std::set<std::string> tempSet(vecRef.begin(), vecRef.end()); //sets only allow unique elements! just stuff the whole vector in, then:
vecRef.clear();
vecRef.assign(tempSet.begin(), tempSet.end());
}示例2: parallelHelper
//Worker function. Start and end represent the #pragma line and the closing brace
//Drives all the work for a parallel
void parallelHelper(int start, int end)
{
//grab the necessary values from the #pragma line
std::string pragmaString = input.at(start);
strvec privVars = getConstructVars(pragmaString, "private");
strvec sharedVars = getConstructVars(pragmaString, "shared");

//save the values in a backup for redeclaration in an inner function
privVarBackup.clear();
for (int i = 0; i < privVars.size(); i++)

}
sharedVarBackup.clear();
