طريقة عمل لعبة الثعبان بلغة ++Snake Game in C
كود لعبة الثعبان الشهيره في جميع اجهزة الموبايل القديمه وهذه اللعبه محببه لدى العديد من الاشخاص ويفضلها كثير من الاشخاص ايضا سواء كبير او صغير السن لان فكرتها ببساطه انه يوجد ثعبان كل مهمتك انك تجعله ياكل الحرف الموجود في المساحه بدون ان يلمس الثعبان نفسه فان لمس الثعبان نفسه فسوف تخسر ومع كل مره يلتهم فيها الثعبان الحروف يكبر وهذه فكره اللعبه باختصار لمن لا يعرفها ، ولا اعتقد انه لا يوجد شخص الى الان لايعرفونها خلافا عن الجيل الجديد ( جيل الايباد ) لانه ربما لم يراها لانه عندما ولد وجد الاجهزه اللوحيه فلا اطيل عليكم في الموضوع وسنتوجه الى الكود
