Read the contents of the txt-file

Answer 1

There are several ways to read the contents of a TMT file in C++:
1. Read in line by line:
- First, add the header files `#include`,`#include`.
- Then, define the function `void readTxe (string file)`. In the function, create the `ifstream` object `infile`, use `infile.open (file.data ())` to connect the file stream object with the file, and then use `assert (infile.is_open ())` to handle the error. If the file fails to open, an error message will be output and the program will be terminated. After that, use `string s` to receive the contents of each line, read and output the contents of the file line by line through `while (getline (infile, s)){cout <<s <<endl;}` loop, and finally use `infile. close ()` to close the file input stream.
2. Character by character reading (ignoring spaces and carriage returns):
- Similarly, add the header file above and define the `void readTxe (string file)` function, create the `ifstream` object `infile` and open the file. After error handling, use `charc` to receive characters, and use `while (! infile. eof ()){infile>> c; cout <<c <<endl;}`Loop to read the characters one by one (ignoring spaces and carriage returns) and output them, and finally close the file input stream.
3. Character by character reading (including spaces and carriage returns):
- First, add the header file and define the function. Then, create the `ifstream` object, open the file, and handle the error. Then, use `charc` to receive the characters. First, set `infile>> noskipws`, and then use `while (! infile. eof ()){infile>> c; cout <<c <<endl;}`Loop to read the characters one by one (including spaces and carriage returns) and output them, and finally close the file input stream.

To view the contents of a TMT file in C#, you can use `Read AllText` to simply display the contents of the text. If you want to modify or assign values to the text, you can use `Read AllLines` because it returns an array of strings. You can analyze and assign values to the elements in the array.

For example, when using `Read AllText`:
```csharp
//relative path: find the path of the current program
FileInfo fileInfo = new FileInfo("TextFile1.txt");
//specify the file path. Because the text and code are under the same path, the relative path is used directly.
Console.WriteLine(File.ReadAllText(fileInfo.FullName));
```
When using `Read All Lines`:
```csharp
//relative path: find the path of the current program
FileInfo fileInfo = new FileInfo("TextFile1.txt");
//specify the file path. Because the text and code are under the same path, the relative path is used directly.
string[] lines = File.ReadAllLines(fileInfo.FullName);
foreach (string line in lines)
{
//Here, you can analyze and assign values to each line.
Console.WriteLine(line);
}
