Tell me, please, what is the error:

#include <iostream> #include <vector> using namespace std; template <typename T> void fillArray(vector<T> &arr) { T el; int size; cout << "Enter the number of elements: "; cin >> size; for (int i = 0; i < size; i++) { cin >> el; arr.push_back(el); } } template <typename T> void printArray(vector<T> arr) { for (int i = 0; i < arr.size(); i++) { cout << arr[i] << " | "; } cout << endl; } template <typename T> void removeEverySecond(vector<T> &arr) { for (int i = 0; i < arr.size(); i++) { if (i % 2 == 1) { arr.erase(arr.begin() + i); } } } int main() { vector<int> intVector; vector<string> stringVector; vector<float> floatVector; cout << "Filling intVector: " << endl << endl; fillArray(intVector); cout << "Filling stringVector: " << endl << endl; fillArray(stringVector); cout << "Filling floatVector: " << endl << endl; fillArray(floatVector); cout << "Printing intVector: " << endl << endl; printArray(intVector); cout << "Printing stringVector: " << endl << endl; printArray(stringVector); cout << "Printing floatVector: " << endl << endl; printArray(floatVector); cout << endl << "Removing..." << endl; removeEverySecond(intVector); removeEverySecond(stringVector); removeEverySecond(floatVector); system("pause"); return 0; }

I get the error: binary ">>": not found an operator accepting the right operand of type "T" (or there is no acceptable conversion). Thanks in advance for your help.

    Try to give the full error message. In addition to what you quoted, the compiler also told you that the error occurs for T == std::string .

    The error occurs because you forgot to make

     #include <string>
    • I made such a mistake ... Thank you very much. - Andrey_Raf
    • @Andrey_Raf, if the answer satisfies you, please accept it by clicking the check mark. And about the error: I somehow even managed to send a bug report to Microsoft that the compiler broke after the update, although I myself fell victim to the same error :) - ixSci
