Question

Subject: Object Oriented Programming (OOP)

Q3: Question # 3 [20] Will the following code compile? If it does not, state the errors. If it does compile, write the output. //Function.cpp #include <iostream> using namespace std; void printData (long i) cout<<"In long print Data "«<i<<endl; } void printData(int i) cout<<"In int printData "<<i<<endl; ) void printData(float i) { cout<<"In float printData "<<i<<endl; ) int main() int i = 10; printData(i); printData((float) i); print Data (20L); return 0; }

Please kindly solve the above two questions as soon as possible would be really grateful to a quick solution. would give a thumbs up.

Thank you!

Answer 1

Question 3 :

The question compiles successfully.

Output :

In int printData 10 In float printData 10 In long printData 20

Execution :

7 1 #include<iostream> 2 #include<vector> 3 using namespace std; 4 5 void printData(long i) //for long 6-{ cout<<"In long printData "«<i<<endl; 8 } 9 void printData(int i) //for int 10 - { 11 cout<<"In int printData "«<i<<endl; 12} 13 void printData(float i) //for float 14 { 15 cout<<"In float printData "«<i<<endl; 16 } 17 18 19 int main() 20 - { 21 int i = 10; //int printDatoci, con i input In int printData 10 In float printData 10 In long printData 20 22

Question 4 :

a.

The code will compile with an error that _getch() was not declared in this scope.

Compilation failed due to following error(s). main.cpp: In function 'int main()': main.cpp:18:12: error: '_getch' was not declared in this scope _getch();

But if we remove _getch() then the output will be :

А B D End ofprogram

Execution:

1 2 #include <iostream> 3 4 using namespace std; 5 6 int maino 7- 8 char i, j, k; 9 i = 'A'; 10 cout<<i<<endl; //print i i.e 'A' 11 j = 'B'; 12 cout<<j<<endl; //print ; i.e 'B' 13 k = "C'+1; //this k will become D 14 cout<<k<<endl; //print 'D' 15 16 cout<<"ENd of" 17 "program" ; 18 //_getch(); //here I didn't used _getch 19 return 0; 20 } 21 input A B D END ofprogram

b.

The code will compile with an error that _getch() was not declared in this scope.

Compilation failed due to following error(s). main.cpp: In function 'int main()': main.cpp:18:12: error: '_getch' was not declared in this scope _getch();

But if we remove _getch() then the output will be :

65 66 68 End of program

Execution :

1 #include <iostream> 4 7 3 using namespace std; 5 int main() 6- { int i, j, k; 8 i 'A'; //ASCII value of A is 65 so it get stored in i 9 cout<<i<<endl; 10 j = 'B'; //ASCII value of B is 66 11 cout<<j«<endl; 12 k = 'C'+1; //ASCII value of C is 67 + 1 = 60 13 cout<<k<<endl; 14 15 cout<<"End of program"; 16 // _getch(); 17 18 19 return 0; 20 } 21 input 65 66 68 End of program

c.

Code :

#include<iostream>
using namespace std;

int main()
{
  
cout<<"One Double Quote : \""<<endl; //print single double quote
cout<<"Two Double QUote : \"\""<<endl; //print two double quote
cout<<"Backslash : \\"<<endl; //print backslash
  
return 0;
}

Output :

One Double Quote : Two Double Quote Backslash : 1

Execution :
