求一段c语言源程序代码！

求一段c语言源程序代码！

一、求一段c语言源程序代码！

int main()

{

int a=3,b=2,c=2.5;

float y=0;

y=(float)(a+b)/3(“%f”,y);

return 0;

}

二、C++程序源代码

程序源码如下； #include “stdafx.h” #include “iostream” using namespace std; template class seqstack { t data[maxsize]; int top; public: seqstack(); t pop(); void push(t x); t top(); bool empty(); }; template seqstack::seqstack() { top=-1; } template t seqstack::pop() { t x; if(top==-1){cerr<<“下溢”;exit(1);} x=data[top]; top–; return x; } template void seqstack::push(t x) { if(top==maxsize-1){cerr<<“上溢”;exit(1);} top++; data[top]=x; } template t seqstack::top(

三、用C++编写的小游戏源代码

以下是贪吃蛇源代码：

void gotoxy(int x,int y)//位置函数

{

COORD pos;

pos.X=2x;

}

void color(int a)//颜色函数

{

SetConsoleTextAttribute(GetStdHandle(STD_OUTPUT_HANDLE),a);

}

void init(int apple[2])//初始化函数（初始化围墙、显示信息、苹果）
