如何检查文件中的最后一个字符？ [英] How Do I Check Last Character In File ?

问题描述

大家好。



我想检查输入文件如：if ch == if语句输入文件中的最后一个字符。我怎么能这样做。 in C ++

Hello everyone

I want to check input file like : if ch==the last character in input file in if statement.How can I do that. in C++

while(!inputFile.eof())
	 {
 inputFile.get(my_character);
if(myquestion)
{
.....
}

我做了

I did

while(inputFile >> character_count)
	{
		character__count++;
	}

然后我还有另一个while循环

and then also I have another while loop

while(inputFile.get(ch))
{
count++;

if(count==character__count++)

{
do something
}
}

所以我做了这个，但我想要不同的解决方案如何使用ifstream检查这个classes

So I did this but I want different solution how can I check this by using ifstream classes

推荐答案

基于理查德的建议：

请看：http://whitefirer.org/cplusplus.fuction/reference/iostream/istream/seekg.html [ ^ ]

该示例调用 seekg（0，ios :: end）; 你应该用-1而不是0来调用
seekg（ 0，ios :: beg ）返回文件的开头并开始处理。

Based on Richard's advice:
Look at: http://whitefirer.org/cplusplus.fuction/reference/iostream/istream/seekg.html[^]
Where that example calls seekg(0, ios::end); you should call with -1 instead of 0
Then read the last character, then seekg(0, ios::beg) to go back to the beginning of the file and start your processing.
