Question

2- Use a conditional operator to fill in the underlined part of the "cout" statement to make the following code prints either “is equal to C++” or “is not equal to C++” depending on value of the string. Put your entire code only inside the blank spaces in parentheses and do not modify other parts of the code. (4 pts):

string st;

cout << "Enter a string:";

cin >> st;

cout << "String " << st <<  

           (........................................................................................) ;

3- Given this code (3 pts)

int n = 5;

if (6 < n < 1)

    cout << "n is greater 6 and less than 1";

else

    cout << "n is not greater 6 and less than 1";

What is the output? Why?

Answer 1

2.

The complete source code is given below:

#include <iostream>
#include <string.h>

using namespace std;

int main()
{
string st;

cout << "Enter a string:";
cin >> st;
  
cout << "String " << st <<((st.compare("is equal to C++")==0)?" is equal to C++":" is not equal to C++");

return 0;
}

OUTPUT:

Enter a string:is not equal to C++
String is is not equal to C++

2.

OUTPUT:

n is greater 6 and less than 1

Explanation:

//variable declarationa and initialization
int n = 5;

//the result of 6<n will be false or 0
//0 < 1 will be true
if (6 < n < 1)
cout << "n is greater 6 and less than 1";
else
cout << "n is not greater 6 and less than 1";

So, the if() condition will be true and the if() block will execute.
