We strongly protest against the insertion of TV series during the advertising time.

Recently, I found that my daughter liked TV ads very much. As soon as the advertising time was reached, she stared at the TV and couldn't stop it. If she was sitting in front of her, she would turn her head to the other side and then watch it, after the advertisement was completed, she immediately cried or turned to play with toys. We all said that she was strongly protesting against the insertion of TV series

Talk C Chestnut Bar (fourth time: C-language example-Fibonacci series)
