我该如何编写这个C代码？ [英] How do I write this C code?

问题描述

问题是：



用for循环重写以下程序段：



< pre lang =c ++> count = 0 ;
i = 0 ;
while （i< n）{
scanf（ ％d，& X）;
if （X == i）
++ count;
++ i;
}

请帮帮我。如果愿意，请写出代码并解释原因。我知道怎么写for循环;但是，由于这个代码的设置方式，我很困惑，需要帮助。请不要使用我不知道的任何C ++语言，因为我只是在编程基础课程中而且我目前只学习C.

解决方案

它实际上非常很简单，你只需要阅读for循环和while循环的工作原理。最好不要给你一个答案，而是给你一些指示。



for循环C [ ^ ]



在C中循环时 [ ^ ]



第3课：循环 [ ^ ]



你还应该学习并理解++ i和i ++的执行之间的区别。

谢谢大家的帮助。我只是误读了代码。答案是

 count =  0 ; 
 
  for （i =  0 ; i <  n; ++ i）; 
 {
 scanf（ ％d，& X）; 
  if （X == i）
 {
 ++ count; 
} 
} 

出于某种原因，if语句在我脑海中没有产生共鸣所以我复杂化了这个问题。但是，谢谢大家的意见。

The question is:

Rewrite the following program segment with a for loop:

count = 0;
i = 0;
while (i < n) {
	scanf("%d", &X);
	if (X == i)
	      ++count;
	++i;
}

Please help me. If you would, please write out the code and explain why. I know how to write a for loop; however, because of how this code is set up, I am confused and in need of help. Please do not use any C++ language that I would not know since I am only in a Programming Fundamentals class and I am only currently learning C.

解决方案

It is actually very simple and you only need to read up on how a for loop and a while loop works. It is better not to give you an answer, but to give you some pointers instead.

for loop in C[^]

while loop in C[^]

Lesson 3: Loops[^]

You should also learn and understand the difference between the execution of ++i and i++.

Thank you everyone for the help. I simply misread the code. The answer is

count = 0;

for (i = 0; i < n; ++i);
{
    scanf("%d", &X);
    if (X == i)
    {
        ++count;
    }
}

For some reason the if statement didn't resonate in my head that it was there, so I over complicated the problem. But thank you everyone for your input.
