Suppose that num is an int variable and discard is a char variable. Assume the f

Question

Suppose that num is an int variable and discard is a char variable.
Assume the following input data:
#34
What value (if any) is assigned to num and discard after each of the following statements executes? (Use the same input for each statement.)
a. cin.get (discard);
cin >> num;
b. discard = cin.peek();
cin >> num;
c. cin.get (discard);
cin.putback (discard);
cin >> discard;
cin >> num;
7. Suppose that name is a variable of type string. Write the input statement to read and store the input Melinda Clinton in name. (Assume that the input is from the standard input device.)

Explanation / Answer

a)

#include <iostream>
using namespace std;

int main()
{
int num;
char discard;

cout << "Enter values: ";

cin.get (discard);
cin >> num;

cout << "You entered " << endl;
cout << "num : "<< num << endl;
cout << "discard : " << discard << endl;

return 0;
}

output :

Enter values: #34

You entered

num : 34

discard : #

b)

#include <iostream>
using namespace std;

int main()
{
int num;
char discard;

cout << "Enter values: ";

discard = cin.peek();
cin >> num;

cout << "You entered " << endl;
cout << "num : "<< num << endl;
cout << "discard : " << discard << endl;

return 0;
}

output :

Enter values: #34

You entered

num : 0

discard : #

c)

#include <iostream>
using namespace std;

int main()
{
int num;
char discard;

cout << "Enter values: ";

cin.get (discard);
cin.putback (discard);
cin >> discard;
cin >> num;
  
cout << "You entered " << endl;
cout << "num : "<< num << endl;
cout << "discard : " << discard << endl;

return 0;
}

output:

Enter values: #34

You entered

num : 34

discard : #

7)

#include <iostream>
#include <string>
using namespace std;

int main()
{
string name;

cout << "Enter name ";
  
getline(cin,name);
  
cout << "You entered " << endl;
cout << "name : "<< name << endl;

return 0;
}

output :

Enter name Melinda Clinton

You entered

name : Melinda Clinton
