问题描述
我想知道我在这里做错了什么。我正在尝试通过void函数对ofstream进行引用并写入我的outfile
Hi, I want to know what I'm doing wrong here. I'm trying to make a reference to the ofstream and write to my outfile through a void function
void border(ofstream& outfile2);
int main()
{
ofstream outfile2;
ifstream infile;
infile.open("prog4.txt"); //opens the data fike
outfile2.open("outfile.txt");
border(a)
}
void border(fstream& outfile2) {
outfile << "@@@@@@ test @@@@@@\n";
return;
}
我没有得到任何我的outfile上的输出
Im not getting any output on my outfile
推荐答案
int main （）$
{
int main()
{
ofstream outfile2;
ifstream infile;
infile.open（QUOT; prog4.txt"）; //打开数据fike
outfile2.open（" outfile.txt"）;
ofstream outfile2;
ifstream infile;
infile.open("prog4.txt"); //opens the data fike
outfile2.open("outfile.txt");
border（a）
什么是"a"，以及如何与infile或outfile2相关？
What's "a", and how, if at all, is it related to infile or outfile2?
此外，这一行缺少分号。
Also, this line is missing a semicolon.
什么是outfile，以及如果有的话它与outfile2有关吗？
What's outfile, and how, if at all, is it related to outfile2?
这篇关于从void函数对offile的流引用的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持！
