double i;



for this code i get in output 1e+10

but how i can get output 10000000000 using cout<< and double variable

it is not working there is no display, i need information about "fixed" u used

Find info here about std::fixed. google is your good programming buddy, learn to use it.

#include <iostream>
#include <cmath>

int main()
   double x = pow(10.0,10.0);
   std::cout << std::fixed << x << '\n';
