#include <chrono.h>

#include <stdlib.h>

#include <iostream.h>

#include<conio.h>

#include <iomanip.h>

//#include <string.h>

#include <fstream.h>







//using namespace std;




int main(int argc, char * argv[])

auto st=high_resolution_clock::now();

float sum = 0;

float a=0;

//myfile >> a;

int i=0;

while (!myfile.eof())

{

   myfile >> a;

   sum+=a;

}




myfile.close();

auto stp=high_resolution_clock::now();

auto dur=duration_cast<microseconds>(stp-st);

cout<<"Total time taken ="<<dur.count()<<"ms"<<endl;// displaying time taken

cout<<"Sum of integers: "<<sum<<endl; // displaying results




getch();

return 0;

}

can someone please tell me what is wrong with this code. Its C++ programming

Answer 1

Below is the modified version of your code :

The only error you were facing is that your code needs type casting . please go through this code below

#include <chrono>

#include <stdlib.h>

#include <iostream>

//#include<conio>

#include <iomanip>

//#include <string.h>

#include <fstream>

using namespace std;

int main(int argc, char * argv[])

{

ifstream myfile;

myfile.open("Input.txt");

//auto st=high_resolution_clock::now();
auto st = std::chrono::high_resolution_clock::now();

float sum = 0;

float a=0;

//myfile >> a;

int i=0;

while (!myfile.eof())

{

   myfile >> a;

   sum+=a;

}

myfile.close();

auto stp=std::chrono::high_resolution_clock::now();

//auto dur=duration_cast<microseconds>(stp-st);
auto dur = std::chrono::duration_cast<std::chrono::milliseconds>(stp - st);

cout<<"Total time taken ="<<dur.count()<<"ms"<<endl;// displaying time taken

cout<<"Sum of integers: "<<sum<<endl; // displaying results

getch();

return 0;

}
