This program uses an infinite while loop to produce a rolling display of owls.
Owls? Yes, owls. Admittedly, they look a bit more like parrots, but times are hard.
Each, erm... owl is displayed using several cout statements. Remember that the \ backslash character in C++ is used to precede one or more "special" characters, such as \n for newline, \t for tab or \e for an escape-sequence. To display a backslash character, it is necessary to use the \\ double-backslash.
Select and copy the C++ source-code at the bottom of this post.
Paste into a text editor, such as Nano or Geany.
Then save the new file, ending in .cpp
I used owls.cpp
To compile from the command-line:
g++ -o owls.cpp owls
To run from the command-line:
./owls
Code is below...
#include <iostream> // For screen output
#include <unistd.h> // For sleep function to pause program
using namespace std; // Standard identifer names for cout and endl
int main()
{
// Handy identifiers for ANSI colour escape sequences
string YELLOW = "\e[33m";
string GREEN = "\e[32m";
string WHITE = "\e[0m";
// Infinite while loop
while ( true )
{
// Top of head is green
cout << GREEN;
cout << " +-----+ " << endl;
cout << " | ";
// White eyes
cout << WHITE;
cout << "O O";
// More of body, green
cout << GREEN;
cout << " |" << endl;
cout << "/| ";
// Yellow beak
cout << YELLOW;
cout << "v";
// Rest of body is green
cout << GREEN;
cout << " |\\" << endl;
cout << "/| |\\" << endl;
// Feet
cout << " +-";
cout << YELLOW;
cout << "+";
cout << GREEN;
cout << "-";
cout << YELLOW;
cout << "+";
cout << GREEN;
cout << "-+" << endl;
// Wait 3 seconds before next owl
sleep(3);
} // end of while loop
return 0;
}
