将一文件修改后保存为另一文件

做作业时遇到的处理数据的小代码

//将一文件修改后保存为另一文件

#include 
#include 
#include 
using namespace std;

int main()
{
	ifstream infile;
	infile.open("C:\\Users\\Administrator\\Desktop\\test1.txt");
	cout << "Reading from the file" << endl;
	string data;
	ofstream outfile;
	outfile.open("修改版.txt");
	while (infile >> data) {
		for (size_t i = 0; i < data.size() - 1; ++i) {
			if (data[i] == ',') {
				data[i] = ' ';
			}
		}
		//在读取文件时，遇到回车时相当于完成一段的读取，这里输出时以endl结尾，相当于加上了原来的回车
		outfile << data << endl;;
		cout << data << endl;
	}
	outfile.close();
	infile.close();

	return 0;
}
