偷吃水果编程
① c语言编程：如果梨子一斤3元，橙子一斤2元，香蕉两斤1元。用45元正好买45斤水果
#include<stdio.h>
int main(){
int pear=3;
int org=2;
int ban=0.5;
int i , j , k;//i , j , k分别表示梨、橙子、香蕉的数量（单位斤）
for( i=0; i<45; i++){
for( j=0; j<45; j++){
for( k=0; k<45; k+=2){
if( pear*i + org*j + ban*k == 45 && i+j+k==45){
printf("梨子：%d，橙子：%d，香蕉：%d
" , i , j , k);
}
}
}
}
}
② 偷吃水果违法吗
一个盗窃犯就是从一个不起眼的小小偷窃行为发展成的，偷水果吃虽不违法也不会留下违法记录给他一个教育是必须的。
③ 不好意思，请教一下，关于计算机操作系统的，吃水果问题。 谢谢~
int mutex=1,s1=0,s2=0,s3=0;
father:{
wait(mutex);
if(s3==0) {signal(s1);s3+=1;}
signal(mutex);
}
daughter:{
wait(mutex);
wait(s1);s3-=1;
signal(mutex);
下面的mother ,son类似
④ 计算机操作系统：放，吃 水果问题
你好 ！ 对于你的提问 我深有体会 因为我也和你一样 天天对着电脑 有时还掉眼泪呢 我有一些方法 希望对你有用噢 ：防电脑辐射有妙招 关键词语：注意酌情多吃一些胡萝卜、豆芽、西红柿、瘦肉、动物肝等富含维生素A、C和蛋白质的食物，经常喝些绿茶等等。 使用电脑时，最好在显示器前配备质量较好的防辐射屏。注意酌情多吃一些胡萝卜、豆芽、西红柿、瘦肉、动物肝等富含维生素A、C和蛋白质的食物，经常喝些绿茶等等。 对于生活紧张而忙碌的人群来说，抵御电脑辐射最简单的办法就是在每天上午喝2至3杯的绿茶，吃一个橘子。茶叶中含有丰富的维生素A原，它被人体吸收后，能迅速转化为维生素A。维生素A不但能合成视紫红质，还能使眼睛在暗光下看东西更清楚，因此，绿茶不但能消除电脑辐射的危害，还能保护和提高视力。如果不习惯喝绿茶，菊花茶同样也能起着抵抗电脑辐射和调节身体功能的作用。 电脑辐射是不可避免的，但可以减少。首先，应尽可能购买新款的电脑，一般不要使用旧电脑，旧电脑的辐射一般较厉害，在同距离、同类机型的条件下，一般是新电脑的1－2倍。操作电脑时最好在显示屏上安一块电脑专用滤色板以减轻辐射的危害，室内不要放置闲杂金属物品，以免形成电磁波的再次发射。使用电脑时，要调整好屏幕的亮度，一般来说，屏幕亮度越大，电磁辐射越强，反之越小。不过，也不能调得太暗，以免因亮度太小而影响效果，且易造成眼睛疲劳。还要注意与屏幕保持适当距离。离屏幕越近，人体所受的电磁辐射越大，因此较好的是距屏幕半米以外。 电脑使用后，脸上会吸附不少电磁辐射的颗粒，要及时用清水洗脸，这样将使所受辐射减轻70％以上。 仙人掌除了可以攻击坏人，还有一项好处喔！据说在计算机桌前放置一仙人掌有助于减少辐射。 常用电脑的人会感到眼睛不适，视力下降，易有疲劳的感觉。常用电脑的人在饮食上应注意以下几方面： 吃一些对眼睛有益的食品，如鸡蛋、鱼类、鱼肝油、胡萝卜、菠菜、地瓜、南瓜、枸杞子、菊花、芝麻、萝卜、动物肝脏等。 多吃含钙质高的食品，如豆制品、骨头汤、鸡蛋、牛奶、瘦肉、虾等。 注意维生素的补充：多吃含有维生素的新鲜水果、蔬菜等。 注意增强抵抗力：多吃一些增强机体抗病能力的食物，如香菇、蜂蜜、木耳、海带、柑桔、大枣等。 吃一些抗辐射的食品：电脑虽然对人体健康影响较小，但也应预防。饮茶能降低辐射的危害，茶叶中的脂多糖有抗辐射的作用。螺旋藻、沙棘油也具有抗辐射的作用。 另外，用完电脑应洗脸，平时应注意锻炼身体。 电脑摆放位置很重要。尽量别让屏幕的背面朝着有人的地方，因为电脑辐射最强的是背面，其次为左右两侧，屏幕的正面反而辐射最弱。以能看清楚字为准，至少也要50厘米到75厘米的距离，这样可以减少电磁辐射的伤害。 注意室内通风：科学研究证实，电脑的荧屏能产生一种叫溴化二苯并呋喃的致癌物质。所以，放置电脑的房间最好能安装换气扇，倘若没有，上网时尤其要注意通风。 面对电脑时间长了不好，那该怎么办？其实每天四杯茶，不但可以对抗辐射的侵害，还可保护眼睛。 1.上午一杯绿茶： 绿茶中含强效的抗氧化剂以及维生素C，不但可以清除体内的自由基，还能分泌出对抗紧张压力的荷尔蒙。绿茶中所含的少量咖啡因可以刺激中枢神经，振奋精神。不过最好在白天饮用，以免影响睡眠。 2.下午一杯菊花茶： 菊花有明目清肝的作用，有些人就干脆用菊花加上枸杞一起泡来喝，或是在菊花茶中加入蜂蜜，都对解郁有帮助。 3.疲劳了一杯枸杞茶： 枸杞子含有丰富的β胡萝卜素、维生素B1、维生素C、钙、铁，具有补肝、益肾、明目的作用。其本身具有甜味，可以泡茶也可以像葡萄干一样作零食，对解决“电脑族”眼睛涩、疲劳都有功效。 4.晚间一杯决明茶： 决明子有清热、明目、补脑髓、镇肝气、益筋骨的作用，若有便秘的人还可以在晚餐饭后饮用，对于治疗便秘很有效果。 还有些最适合计算机族喝的茶饮，或是点心，不但可以帮您对抗辐射的侵害，还可保护您的眼睛，抗烦躁呢。 绿豆薏仁汤 绿豆可以清热解毒、利尿消肿，薏仁则可以健脾止泻，轻身益气，对于经常需要熬夜工作者或是心烦气躁、口干舌燥、便秘、长青春痘时，除了多吃蔬菜水果与补充水份外，把绿豆薏仁汤当点心食用，对于消暑除烦非常有帮助。 杜仲茶 杜仲具有补血与强壮筋骨的作用，对于经常久坐，腰虽背痛很有帮助，男女都可以喝，若是女性朋友还可以在生理期的末期与四物汤一起服用 来源:

⑤ c语言编程题目关于卖水果
#include"stdio.h"
intmain()
{
inti,sum[8];
sum[7]=5;//第八天的水果数，数组从0开始计数，所以是sum[7]
for(i=7;i>0;i--)//从第八天向前算
{
sum[i-1]=(sum[i]+2)*3;//通过公式x-(2/3x+2)=5推导而来
}
printf("%d",sum[0]);//总的水果数
return0;
}
有什么疑问请追问
⑥ 求指教:用c语言写吃苹果问题，原理是操作系统同步与互斥 父亲往盘子里放一个苹果，儿子取一个吃，且盘
您好，有个例子，对您有用：
同步关系
设信号量e（表示盘子为空），a（表示盘子里是苹果），o（表示盘子里是桔子）
int e=1,a=o=0;
main()
{father();
//son();
//daughter();/*三个为并发进程*/
}
father()
{while(1)
{ 洗水果
wait(e)
把水果放入盘子
if（水果是苹果）signal(a)
else signal(o)
}
}
son()
{while(1)
{wait(o)
从盘子里取桔子
signal(e)
吃桔子}
}
daughter()
{while(1)
{wait(a)
从盘子里取苹果
signal(e)
吃苹果}
}
⑦ 求C语言编程实例电脑版切水果源代码
切水果不可能是C语言版的，C语言还做不到那么高级的图形处理，一般是Android工程的java代码，当然底层可能有部分C/C++代码。
⑧ 麻烦给完整编程
print('\n'.join(input('请输入多种水果名称：').strip().split()))
⑨ c语言编贪吃蛇，用什么编译环境，怎么显示贪吃蛇和水果，怎么键盘响应我菜鸟都不算，求指教。
