Question

1. What is the output of the following code segment? (Write "infinite loop" if the loop never ends.)

string str = "stressedOUT";
for (string::size_type index = str.length() - 1; index != string::npos; --index)
{
    if (str[index] != 'O' && str[index] != 'U' && str[index] != 'T')
        cout << str[index];
}
cout << endl;

Explanation / Answer

1. What is the output of the following code segment? (Write "infinite loop" if the loop never ends.)

string str = "stressedOUT";
for (string::size_type index = str.length() - 1; index != string::npos; --index)
{
    if (str[index] != 'O' && str[index] != 'U' && str[index] != 'T')
        cout << str[index];
}
cout << endl;

Program:

#include <iostream>
using namespace std;

int main() {
   string str = "stressedOUT";
for (string::size_type index = str.length() - 1; index != string::npos; --index)
{
if (str[index] != 'O' && str[index] != 'U' && str[index] != 'T')
cout << str[index];
}
cout << endl;
   return 0;
}

Output:

desserts

Answer: desserts

2. Program

#include <iostream>

using namespace std;
int foo()
{
int num = 11;
return --num;
}
int bar()
{
static int num = 11;
return --num;
}

int main() {
cout << foo() + foo() + bar() + bar() << endl;
   return 0;
}

Output: 39

Answer: 39

3.Program:

#include <iostream>

using namespace std;
int main() {
string str = "ABCDEFGH";

cout << str.length() << str[str.length() - 1] << endl;
   return 0;
}

Output: 8H

Answwer: 8H

Consider the declaration:
