What will be the output of the following C++ code?

    #include <iostream>
    #include <string>
    using namespace std;
    int main ()
    {
        string str;
        string str2="Steve jobs";
        string str3="He founded apple";
        str.append(str2);
        str.append(str3, 6, 3);
        str.append(str3.begin() + 6, str3.end());
        str.append(5,0x2e);
        cout << str << '\n';
        return 0;
    }

Detailed Solution: Question 3

In this program, We are adding characters to the string, So the output will as follows after addition of characters.
Output:

$ g++ str.cpp
$ a.out
Steve jobsndended apple.....

Test: C++ Strings - Question 4
Save

What will be the output of the following C++ code?

    #include <string>
    using namespace std;
    int main ()
    {
        string str ("I like to code in C");
        unsigned sz = str.size();
        str.resize (sz + 2, '+');
        str.resize (14);
        cout << str << '\n';
        return 0;
    }

Detailed Solution: Question 4

In this program, We are resizing the string by adding + and then we are resizing it to 14.
Output:
$ g++ basicst.cpp
$ a.out
I like to code

    }

Detailed Solution: Question 5

In this program, We are adding the characters at the end of the current value.
Output:
$ g++ str1.cpp
$ a.out
Jobs Apple Steve

Test: C++ Strings - Question 6
Save

What will be the output of the following C++ code?

    using namespace std;
    int main ()
    {
        string str ("Steve jobs founded the apple");
        string str2 ("apple");
        unsigned found = str.find(str2);
        if (found != string :: npos)
            cout << found << '\n';
        return 0;
    }

Detailed Solution: Question 6

In this program, We are finding a string by using the find method.

$ g++ basicst2.cpp
$ a.out
23

Test: C++ Strings - Question 7
Save

What will be the output of the following C++ code?

    #include <iostream>
    #include <string>
    using namespace std;
    int main ()
    {
        string str ("Steve jobs");
        cout << str.length();
        return 0;
    }

        string str ("Steve jobs");
        char * cstr = new char [str.length() + 1];
        strcpy (cstr, str.c_str());
        char * p = strtok (cstr," ");
        while (p != 0)
        {
            cout << p << '\n';
            p = strtok(NULL," ");
        }
        delete[] cstr;
        return 0;
    }

            cout << *it;
        return 0;
    }

Detailed Solution: Question 14

In the for loop, We are not allowed to give a numeric value in string, So it is arising an error.

Test: C++ Strings - Question 15
Save

What will be the output of the following C++ code?

    #include <iostream>
    #include <string>
    using namespace std;
    int main ()
    {
        string str ("Steve jobs");
        cout << str.capacity() << "\n";
