Exercise 1-2

Experiment to find out what happens when printf's argument string contains \c, where c is some character not listed above.
When we compile and execute the code 
    #include <stdio.h>
    
    main()
    {
        printf("\c");
    }
the character 'c' gets printed to the screen. Likewise, the code 
    #include <stdio.h>
    
    main()
    {
        printf("\a");
    }

prints the character 'a' to the screen. Try this with some more characters, and you will find that printf ignores the backslash when the escape sequence is invalid.
