当我创建以下功能时,
int readDataFromFile(ifstream& openFileStream, Snowman data[ ]){
double height;
double weight;
double temp;
bool hat;
string scarf;
int count = 0;
while(openFileStream >> height) {
openFileStream >> weight;
openFileStream >> temp;
openFileStream >> hat;
openFileStream >> scarf;
}
return count;
}
这些部分是错误的;
openFileStream >> height;
openFileStream >> weight;
openFileStream >> temp;
openFileStream >> hat;
openFileStream >> scarf;
结果是:
我将在
ifstream
函数中打开main()
,但是如何将其传递给另一个函数? 最佳答案
看看下面的我的代码段,该代码段可在Windows上使用。注意ans.txt
仅包含2个double值
#include <fstream>
#include <iostream>
void printcontents(std::ifstream& inp)
{
double val1, val2;
while (inp)
{
inp >> val1;
inp >> val2;
}
std::cout << val1 << " " << val2 << std::endl;
}
int main()
{
std::ifstream inp("C:\\somefolder\\ans.txt");
printcontents(inp);
