Rewrite the following C++ Program after removing any/all syntactical error(s). Underline each correction done in the code:

Note: Assume all required header files are already included in the profram.

#define Area(L,B) = L*B
structure Recta
{
  int Length, Breadth;
};
  void main()
{
  Recta R= [10, 15];
  cout<<Area(Length.R, Breadth.R);
}

Write a program to collect follow entry about an student in a structure type c++ data structure.
integer – rollno, char array – name, float – marks and char passfail. Declare a global instance of this structure and then collect the rollno,name and marks in the main routine. Within the main routine update the value of passfail as ‘Y’ or ‘N’ if the marks are more than or equal to 33.0 . Finally it should report as per following example.

R.No. Name Marks Status

Write the output of the following program.

Find the errors in the following structure declaration.

struct Computer {
 char type[40]="Laptop";
 char p;
 Computer comp;
 float price; 
};c1[20]

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

struct Game {
  char Magic[20];int Score;
};

int main()
{
  Game M={"Tiger",500};
  char a[20];
  cout<<M.Magic<<", "<<M.Score<<endl;
  strcpy(a,M.Magic);
  a[0]='L'; a[2]='o'; a[3]='n'; a[4]='';
  strcpy(M.Magic,a);
  M.Score++;
  cout<<M.Magic<<", "<<M.Score<<endl;
  return 0;
}

Write the main differences between structure and array

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.

struct Employee{double salary,hra;};
void change(Employee &a,double h=100)
{
  a.salary+=1000;
  a.hra+=h;
}   
int main() 
{ 
  Employee A={5000,2000};
  cout<<"Initial Payment  = "<<A.salary+A.hra<<endl;
  change(A,500);
  cout<<"After 1st Change = "<<A.salary+A.hra<<endl;   
  change(A);
  cout<<"After 2nd Change = "<<A.salary+A.hra<<endl;
  return 0; 
}

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