Problem Statement - Output writing using structure copy and strcat use

struct Play {char Arr[20];int n;}; 
int main() 
{ 
  struct Play P={"JUDO",2};
  P.Arr[0]='L';
  P.n+=2; 
  cout<<P.Arr<<"#"<<P.n<<endl;   
  Play R = P;
  R.Arr[0]='S';R.Arr[1]='O';
  strcat(R.Arr,"KU");
  R.n-=3; 
  cout<<R.Arr<<"#"<<R.n<<endl; 
  return 0; 
}

Write the output of the above program. Assume that required header files are present.

Solution

TC++ #7684

Run Output 

LUDO#40

SODOKU#1

struct Play P={“JUDO”,2}; //structure initialised with Arr[] content as JUDO and n as 2
P.Arr[0]=’L’; //JUDO becomes LUDO as 0th character changed
P.n+=2;         //n becomes 4 as 2 is added to previous value
cout<<P.Arr<<“#”<<P.n<<endl;  //LUDO#4 printed
Play R = P;  //Another copy of structure object made as R which will have final values as contained in P
R.Arr[0]=’S’;R.Arr[1]=’O’; //R’s arr[] now becomes SUDO
strcat(R.Arr,”KU”); //Additional KU is concatenated to SUDO making it SODUKU
R.n-=3; //R’s n us reduced by 3 making it 1
cout<<R.Arr<<“#”<<R.n<<endl; //SODOKU#1 is printed
