有人能帮我吗？ [英] Can someone help me?

问题描述

这是编码;

#include< iostream>

使用命名空间std;



int getdata_two（int c []，int startcnt，int endcnt）;



main（）{

int a [30] = { 0,1,2,3,4,5,6 ...... 29}

int startcnt [6] = {11,11,19,19,24,24}，endcnt [6] = {16,16,23,23,27,27}，dataval = 68;



if（dataval％2 == 0）

dataval = getdata_one（a，startcnt [0]，endcnt [0]）;

else if（dataval％2 == 1）

dataval = getdata_two（a，startcnt [1]，endcnt [1]）;



switch（dataval％2）{

case 0：

dataval = getdata_three（a，startcnt [2]，endcnt [2]）;

休息;

案例1：

dataval = getdata_four（a，startcnt [3]，endcnt [3]）;

}



int getdata_two（int c []，int startcnt，int endcnt）{

int datacnt = endcnt;

while（startcnt< endcnt）{

datacnt + = c [ startcnt];

startcnt ++;

}

返回datacnt ;

}





//

1）我的第一个问题，

if [（dataval％2 == 0）

dataval = getdata_one（a，startcnt [0]，endcnt [0]）;

否则（dataval％2 == 1）

dataval = getdata_two（a，startcnt [1]，endcnt [1]）;



这是函数调用对吗？现在满足的条件是（dataval％2 == 0），它将调用函数定义---->

int getdata_two（int c []，int startcnt，int endcnt）{<

int datacnt = endcnt;

while（startcnt< endcnt）{

datacnt + = c [startcnt];

startcnt ++ ;

}

返回datacnt;

}



2）什么是意思是datacnt = endcnt？是传输数组的数量是6还是数组中的内容？



3）FOR ---> ;;虽然（startcnt< endcnt），它试图比较的条件是什么？是数组编号（6 <6）还是数组startcnt和endcnt内的总内容分别为108和132？



4）执行完毕后功能定义，它将继续操作---->

switch（dataval％2）{

case 0：

dataval = getdata_three（a，startcnt [2]，endcnt [2]）;

break;

case 1：

dataval = getdata_four （a，startcnt [3]，endcnt [3]）;

}

对吗？它为什么打破了？谢谢你回答我的问题:)



我尝试过：



帮助我们找出编码的路径。 p / s：Sory for bad english

This is the coding;
#include <iostream>
using namespace std;

int getdata_two(int c[],int startcnt, int endcnt);

main(){
int a[30]= {0,1,2,3,4,5,6......29}
int startcnt [6] = {11,11,19,19,24,24}, endcnt[6]={16,16,23,23,27,27},dataval=68;

if (dataval % 2 ==0)
dataval=getdata_one(a,startcnt[0],endcnt[0]);
else if (dataval % 2 ==1)
dataval=getdata_two(a,startcnt[1],endcnt[1]);

switch (dataval % 2){
case 0:
dataval=getdata_three(a,startcnt[2],endcnt[2]);
break;
case 1:
dataval=getdata_four(a,startcnt[3],endcnt[3]);
}

int getdata_two(int c[],int startcnt, int endcnt){
int datacnt=endcnt;
while (startcnt<endcnt){
datacnt+=c[startcnt];
startcnt++;
}
return datacnt;
}


//
1)My first question,
if [(dataval % 2 ==0)
dataval=getdata_one(a,startcnt[0],endcnt[0]);
else if (dataval % 2 ==1)
dataval=getdata_two(a,startcnt[1],endcnt[1]);

this is function call right? Now the condition fulfilled is (dataval % 2 ==0), its gonna call function definition ---->
int getdata_two(int c[],int startcnt, int endcnt){
int datacnt=endcnt;
while (startcnt<endcnt){
datacnt+=c[startcnt];
startcnt++;
}
return datacnt;
}

2) What is meant by datacnt = endcnt? Is it transfer the number of array which is 6 or the content inside the array?

3) FOR --->; while (startcnt < endcnt), whats the condition that its trying to compare to? is it the array number which is (6<6) or the total content inside array startcnt and endcnt which is 108 and 132 respectively?

4) After it carried out the function definition,it will continue the operation which is ---->
switch (dataval % 2){
case 0:
dataval=getdata_three(a,startcnt[2],endcnt[2]);
break;
case 1:
dataval=getdata_four(a,startcnt[3],endcnt[3]);
}
right? Why did it break tho? Thanks for answering my question :)

Help meeee in to figure out the path that this coding go. p/s : Sory for bad english

推荐答案

调试器会显示你的代码在做什么。



您应该尽快学会使用调试器。而不是猜测你的代码在做什么，现在是时候看到你的代码执行并确保它完成你期望的。



调试器允许你跟踪执行逐行检查变量，你会看到它有一个停止做你期望的点。

调试器 - 维基百科，免费的百科全书 [ ^ ]

掌握Visual Studio 2010中的调试 - A初学者指南 [ ^ ]



调试器在这里向您展示您的代码正在做什么，您的任务是与它应该做什么进行比较。 />
调试器中没有魔法，它没有发现错误，它只是帮助你。当代码没有达到预期的效果时，你就接近了一个bug。

The debugger will show you what your code is doing.

You should learn to use the debugger as soon as possible. Rather than guessing what your code is doing, It is time to see your code executing and ensuring that it does what you expect.

The debugger allow you to follow the execution line by line, inspect variables and you will see that there is a point where it stop doing what you expect.
Debugger - Wikipedia, the free encyclopedia[^]
Mastering Debugging in Visual Studio 2010 - A Beginner's Guide[^]

The debugger is here to show you what your code is doing and your task is to compare with what it should do.
There is no magic in the debugger, it don't find bugs, it just help you to. When the code don't do what is expected, you are close to a bug.

我强烈建议你阅读像 C ++语言 - C ++教程 [ ^ ]。



有关（根据你的观点）查询：

I strongly suggest to read a C++ tutorial like C++ Language - C++ Tutorials[^].

There look up about (according to your points):

1. 函数
2. 变量和类型
3. 比较运算符
4. 语句和流控制（循环， break 声明）

1. Functions
2. Variables and types
3. Comparison operators
4. Statements and flow control (loops, break statement)
