Exercise 4.7

1. What is wrong with the following program?

#include <iostream.h>
using namespace std; /
int main()
{
int y = 0;
cout << “xy= “ << y << endl;
return 0;
}

2. Compile and run the following program; thereafter, explain the output.

#include <iostream>
using namespace std;
int main()
{
cout << “Size of char: “ << sizeof(char) << “ byte” << endl;
cout << “Size of integer: “ << sizeof(int) << “ bytes” << endl;
cout << “Size of float: “ << sizeof(float) << “ bytes” << endl;
cout << “Size of double: “ << sizeof(double) << “ bytes” << endl;
return 0;
}

3. Examine the following C++ code and answer the questions that follows.

string str1;
string str2;
char ch;
cin >> str1;
str2 = str1;
cin >> ch;
str2[0] = ch;
cout << str1 << “ –> “ << str2 << endl;
