read integers from a file into a vector in C++
- by user2922063
I am trying to read an unknown number of double values stored on separate lines from a text file into a vector called rainfall. My code won't compile; I am getting the error no match for 'operator>>' in 'inputFile >> rainfall' for the while loop line. I understand how to read in from a file into an array, but we are required to use vectors for this project and I'm not getting it. I appreciate any tips you can give on my partial code below.
vector<double> rainfall; // a vector to hold rainfall data
// open file
ifstream inputFile("/home/shared/data4.txt");
// test file open
if (inputFile) {
int count = 0; // count number of items in the file
// read the elements in the file into a vector
while ( inputFile >> rainfall ) {
rainfall.push_back(count);
++count;
}
// close the file
