C++语言求翻译

f = @(x) sqrt((35*x^4+3)/30); eps = 0.00000001; x0=0.3; x1=f(0.3); while abs(x1-x0)>eps x0=x1; x1=f(x0); end disp(num2str(x1));

如下: #include using namespace std; int main() { cout

输入输出函数改改就好了; #include#includeusing namespace std;void insert(){FILE *fp;int i,j,k,m=0,snum;if((fp=fopen("data.txt","r+"))==NULL){ cout

srand 无法翻译,这是C++里的随即种子,pascal无用 Const inf=10000000000000.0; maxn=155; pn=200; Type line=Record x1,y1,x2,y2:double; End; point=Record x,y,sum:double; End; Var n,i:longint; l:array[0..maxn] of line; p:array[0..pn+1]...

类似c的sscanf sprintf

这是MFC程序的消息映射的宏: ON_WM_CONTEXTMENU右键点击窗口的时候调用OnContextMenu这个函数 ON_COMMAND(ID_ELLIPSE, OnEllipse) 表示点击ID为ID_ELLIPSE的菜单项时就调用OnEllipse函数;其他的ON_COMMAND类似 ON_UPDATE_COMMAND_UI(ID_ELLIPS...

未定义

if(++i%10==1) {printf("%d\t",i);} else {printf("%d\n",i);}

C + + is an efficient and practical programming language, it can process change program design, can also be carried out in the face of the object program design, and easier to learn than C (such as I/O flow, annotation, quote, ...

下面是等效C代码。C++部分已被注释。 cin在错误时终止while循环,等同于scanf读不到合法的整数时离开while循环。 #include //#include //using namespace std; int main() { int n,i,t; //while(cin>>n>>t) while((scanf("%d", &n) == 1) && (sc...
