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:
Following are the code in Java Language:
Scanner sc = new Scanner(System.in); // create a instance of scanner class
DecimalFormat frmt = new DecimalFormat("0.###"); // create a instance of // DecimalFormat class
System.out.println ("Enter the value: ");
double number = scan.nextDouble(); // Read the value by thje user
System.out.println (fmmt.format(Math.pow(number, 4))); // display the value
Explanation:
Following are the description of the code
- Create an instance scanner class i.e "sc".
- Create an instance of DecimalFormat class i.e "frmt".
- Read the value by the user in the "number" variable of type double by using the nextDouble()method.
- Finally, display the value by using System.out.println method. In this, we call the method format. The Math.pow() function is used to calculating the power up to the fourth value.
Answer:
14
Explanation: The reason why is because adding a negative is pretty much subtracting by 2. 9-2=7. Then multiply 7 by 2 like add 7 to 7 and you get 14.
