Answer:
#include <iostream>
using namespace std;
class Str{ ///baseclass
public :
string super_str;
string getStr()
{
return super_str;
}
void setStr(string String)
{
super_str=String;
}
};
class str : public Str{ //inheriting Str publicly
public :
string sub_str;
string getstr()
{
return sub_str;
}
void setstr(string String)
{
sub_str=String;
}
bool notstartswith()
{
int n=sub_str.length(); //to find length of substr
bool flag=false;
for(int i=0;i<n;i++) //Loop to check beginning of Str
{
if(super_str[i]!=sub_str[i])
{
flag=true;
break;
}
}
return flag;
}
};
int main()
{
str s; //object of subclass
s.setStr("Helloworld");
s.setstr("Hey");
if(s.notstartswith()==1) //checking if str is substring of Str
cout<<"Str does not start with str";
else
cout<<"Str starts with str";
return 0;
}
OUTPUT :
Str does not start with str
Explanation:
Above program is implemented the way as mentioned. for loop is being used to check the beginning of the str starts with substring or not.
Answer:
The answer to this question is given below in the explanation section.
Explanation:
The correct answer to this question is c)field.
As we know that the feature of an entity is represented by its attribute in the database table. A database table is a set of records of different fields. Each field represents a row in a database table. Each field can contain a set of attributes related to an entity such as a paint color.
So the price of paint will be in its own field. Because there are different colors in the database table. Each color has its own record in form of a field. As you know that each field is a row in the database table. So, each row has the price of a paint color.
Other options are not correct because:
The table contains a list of fields and each field contains its own paint price. The format and file is something different and does not have any relation with the question scenario.
