answer:c

1 #include <iostream> 2 3 using namespace std; 4 5 - int main() { string playerName;//initialize playername 7 cout<<"Enter playerName"; 8 cin>>playerName;//read player name 9 cout<<endl<<playerName; //printing playername 10 return 0; 11 } 0 AWN ✓ Execute Mode, Version, Inputs & Arguments GCC 9.1.0 Interactive CommandLine Arguments Stdin Inputs Tom - Sawyer Execute Result CPU Time: 0.00 sec(s), Memory: 3380 kilobyte(s)compiled and executed in 1 Enter playerName Tom

4) In the given Program the player name as Tom Sawyer. The cour Prints Swing Swing as Tom. before Beatuse, the string takes string * Tom". Space. So, ir Prints white

option:a

NM 1 #include <iostream> 2 3 using namespace std; 4 5 - int main() { 6 string name="Adam";//initialize string name 7 int age=30;//initialize age 8 //printing name and age | 9 cout<<name<<" is "<<age<<" years old"; 10 11 return 0; 12 } Execute Mode, Version, Inputs & Arguments GCC 9.1.0 Interactive CommandLine Arguments Stdin Inputs Execute Result CPU Time: 0.00 sec(s), Memory: 3260 kilobyte(s)compiled and executed in 1 Adam is 30 years old
