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.
They are based on 10 digits.
I’m not sure.
Because it keeps your files, folders, and documents in a consistant logical way.
Answer:
Option D The negative number entered to signal no more input is included in the product
Explanation:
Given the code as follows:
- int k = 0;
- int prod = 1;
- while (k>=0)
- {
- System.out.println("Enter a number: ");
- k= readInt( );
- prod = prod*k;
- }
- System.out.println("product: "+prod);
The line 7 is a logical error. Based on the while condition in Line 3, the loop shall be terminated if k smaller than zero (negative value). So negative value is a sentinel value of this while loop. However, if user enter the negative number to k, the sentinel value itself will be multiplied with prod in next line (Line 7) which result inaccurate prod value.
The correct code should be
- int k = 0;
- int prod = 1;
- while (k>=0)
- {
- prod = prod*k;
- System.out.println("Enter a number: ");
- k= readInt( );
- }
- System.out.println("product: "+prod);
