文本文件如下所示:
this is a test \n to see if it breaks into a new line.
c ++看起来像这样:
string test;
ifstream input;
input.open("input.txt");
getline(input, test);
如果你对输出文件写'test',它看起来像这样:
this is a test \n to see if it breaks into a new line.
我希望它在遇到'\ n'字符时突破到一个新行,因为它被写入文件。

这样做:
#include <fstream>
using namespace std;
int main() {
fstream file;
file.open("test.txt");
string test = "this is a test \n to see if it breaks into a new line.";
file << test;
file.close();
return 0;
}
“text.txt”的结果:
this is a test
to see if it breaks into a new line..

为了获得乐趣,为了获得最高效率,我们可以消除对ID | sample_id | test_id | result_id
的需求,并且无需在编译时通过这样做来计算字符串的长度:
std::string
