Question

I have the following code

#include <iostream>
#include<string>
#include <sstream>
using namespace std;
struct product{
    int weight;
    float price;
};
int main(){
    string  mystr;
    product  prod;
    product *pointer;
    pointer=&prod;
    getline(cin,pointer->price);
    return 0;
}

but it shows me the mistake

no instance of overloaded function “getline” matches argument list

What is the mistake?

Answer 1

The mistake is that getline returns string, not float.

string str;
getline(cin, str);
pointer->price = atof(str.c_str());
