I want to convert string to float with stof but it is not working Also I was enabled c++ 11 in codeblocks but give error me that "stof was not declared in this scope" if I use of std::stof yet give error me that it is not member of std
Here is my code: 

#include <iostream>
#include <string>
using namespace std;
int main()
{
    string x;
    x="23";
    float y=stof(x)+2.1;
    cout<<y;
    return 0;
}

try this:

include <sstream>
std::stringstream ss;
ss << "23";
float f;
ss >> f;

You have declared y to be an integer.

By definition, integers do not have fractional or decimal parts.

When you add 2.1 it will truncate the decimal.
