For the problem “terminate called after throwing an instance of ‘std::invalid_argument’ what(): stoi.” I tried to fix it, but it doesn’t work and returns the result I want. Here is my program:
#pragma once
#include <string>
#include <vector>
#include "Task.h"
#include <ostream>
#include "ARAIG_Sensors.h"
namespace m1
{
class Profile
{
ARAIG_Sensors araig;
std::vector<Task> ToRun;
std::vector<Task> Completed;
std::string studentFN;
std::string studentLN;
std::string studentSN;
std::string flightFN;
std::string flightLN;
std::string flightEN;
std::ostream& os;
struct calibration {
int Max;
int Min;
};
calibration cal;
public:
Profile(std::string fn, std::ostream& o, ARAIG_Sensors& a) : os(o)
{
araig = a;
//parsing student
std::ifstream infile(fn);
std::string line;
std::getline(infile, line);
int f = line.find_first_of(",");
studentFN = line.substr(0, f);
line = line.substr(f + 1);
f = line.find_first_of(",");
studentLN = line.substr(0, f);
studentSN = line.substr(f + 1);
//parsing flight
std::getline(infile, line);
f = line.find_first_of(",");
flightFN = line.substr(0, f);
line = line.substr(f + 1);
f = line.find_first_of(",");
flightLN = line.substr(0, f);
flightEN = line.substr(f + 1);
//parsing calibration
std::getline(infile, line);
f = line.find_first_of(",");
cal.Min = stoi(line.substr(0, f));
std::cout << cal.Min << std::endl;
line = line.substr(f + 1);
cal.Max = stoi(line);
std::list<Task> temp = araig.gettasks();
while (std::getline(infile, line))
{
for (std::list<Task>::iterator i = temp.begin(); i != temp.end(); i++)
{
if ((*i).getName() == line)
{
ToRun.push_back(*i);
break;
}
}
}
}
void displayToRun()
{
for (std::vector<Task>::iterator i = ToRun.begin(); i != ToRun.end(); i++)
{
(*i).execute(os);
}
}
void displayCompleted()
{
for (std::vector<Task>::iterator i = Completed.begin(); i != Completed.end(); i++)
{
(*i).execute(os);
}
}
void displayNext()
{
std::vector<Task>::iterator i = ToRun.begin();
(*i).execute(os);
}
void displayLast()
{
std::vector<Task>::iterator i = Completed.end();
(*i).execute(os);
}
void Run()
{
//excute next Task and move Task to Completed
std::vector<Task>::iterator i = ToRun.begin();
Task t = *i;
t.execute(os);
ToRun.erase(i);
Completed.push_back(t);
}
};
}

terminate called after throwing an instance of 'std::invalid_argument'
what(): stoi
Aborted
has occurred. I’ve checked the entire command line but still can’t find the mistake.
The cause: The error indicates that you provided
stoi
with a string that could not be converted to an integer.Detect the exception and check / print the string that created the issue.
Solution:
To solve the issue software is shutting down, you should use:
block around this:
The findings that produce the exception can then be shown.
This means that
std::stoi()
is receiving bad input. It’s throwing a exception you are not catching.std::stoi, std::stol, std::stoll:
std::terminate
Double-check the input string values you’re trying to convert into integers. They are not integers.
