In C What string will the following code output string str

In C++

What string will the following code output?

string str = “crockpot of ontological orthodoxy”;

string output = “”;

int counter = 1;

while (str.at(counter) != ‘o’)

{

       output += str.at(counter);

       counter += 3;

}

cout << output << endl;

Solution

One can compile the following program using only the main function with the code given (as shown below) written in a file with the name generateString.cpp

//file name: generateString.cpp

#include <iostream>

#include <string>

using namespace std;

int main()

{

string str = \"crockpot of ontological orthodoxy\";

string output = \"\";

int counter = 1;

while ( str.at(counter) != \'o\')

{

output += str.at(counter);

counter += 3;

}

cout << output << endl;

return 0;

}

This program prints the following string on the terminal:

rktfnlilr

The logic is using the given string of \"crockpot of ontological orthodoxy\", starting from 2nd character (ie., from r, then k, then t in crockpot, then f in of etc) print the 3rd character till it becomes \'o\'. This considers blank space also as a character. Thus the output string is rktfnlilr.

On a Unix or linux platform compile the above program using the command g++ generateString.cpp. Then run the program as ./a.out to generate the above string.
