Examples

EX1

int is_in_list_ex1()
{
    vector<string> vsPlaces = {"ShangHai","Shanghai","UK","LA","London","Pary"};
    int iIndex;
 
    if(is_in_list("UK", vsPlaces,true,&iIndex))
        printf("%d\n",iIndex);//Should print 2 since the index starts from 0
 
    string strPlace = "ShangHai";
    if(is_in_list(strPlace,vsPlaces,true,&iIndex))
        printf("%d\n",iIndex);//Should print 0 since the index starts from 0
