Hi! I have a few short questions about C++ Thank you!

1.Given the statement: int list[25]; The index can go from 0 to 25 inclusive without going beyond the end of the array.true or false?

2. The main purpose of a constructor is to initialize the data members at the moment that an object is created. true or false?

3.Given the declaration: int list[50] ; the statement: cout<<list<<endl; outputs all 50 components of the array list on one line. true or false?

4. Given the function prototype: int testBeta(int x, char v, int y); the following statement in the main program is legal.

cout<<testBeta(5, char 'A', int 2); true or false?

5. Suppose x = 10 and y = 20. The value of the expression

((x >= 10) && (y > 20) || (x < y) ) true or false?

THANK YOU!

Explanation / Answer

1. true
2. True

A class constructor is a special member function of a class that is executed whenever we create new objects of that class

3. false

#include<stdio.h>
#include<iostream.h>

void main()
{
int list[50] ;
cout<<list<<endl;
}

output

0x236f2382

4.
false

#include<stdio.h>
#include<iostream.h>

int testBeta(int x, char v, int y);
void main()
{

cout<<testBeta(5,'A',2);
}

5.
true

#include<stdio.h>
#include<iostream.h>

void main()
{

int x,y;
x = 10;y = 20;

if((x >= 10) && (y > 20))
{

cout<<"true1"<<endl;
}
else if ((y > 20) || (x < y) )
{

   cout<<"true2"<<endl;
}
else if((x >=10) || (x < y) )
{
cout<<"true3"<<endl;
}

else
{
cout<<"false"<<endl;
}
}

output
true 2
