Problem :

My stoi function is crashing the program with the error message as below :

"****@****:~> g++ -std=c++0x m1.cpp stimulation.h stims.h Task.h exoskeleton.h ARAIG_Sensors.h Profile.h
ARAIG_Sensors.h:1:9: warning: #pragma once in main file [enabled by default]
Profile.h:1:9: warning: #pragma once in main file [enabled by default]
*****@****:~> a.out StimulationConfig.csv TaskConfiguration.csv SampleProfileConfig.csv SampleOutput.txt
First : a.out
Second : StimulationConfig.csv
terminate called after throwing an instance of 'std::invalid_argument'
what():  stoi
Aborted

I am unable to know why is there the instance being passed to the method but it is still returning the above error. Can somebody help me in resolving the issue?

Solution :

It clearly means that you are giving std::stoi() bad input, that’s why it is throwing the std::invalid_argument exception that you are unfortunately not catching.

std::stoi, std::stol, std::stoll:

Exceptions as below :

· std::invalid_argument : Thrown if no conversion could be performed

· std::out_of_range Thrown if the converted value is out of the range of the result type or if the underlying function std::strtol or std::strtoll is trying to set errno to ERANGE.

std::terminate:

The std::terminate() is called by the C++ runtime when the exception handling fails for the below reason:

If an exception is thrown and not caught :

Here you need to cross-check your input string values that you are converting to integers. As they do not represent the integers.

Problem : I am a Computer Science Student. I am trying to learn the C++ programming. I want to execute a very simple averaging code written by me but I always face below error: Terminate called after throwing an instance of 'std::out_of_range' what(): vector::_M_range_check: ... larger than 0? So I am confused because of above error. Can some expert in C++ guide me in fixing above error for me.

Problem : I am literally trying to start learning C++, and I have written very simple code in C++ as follows for your reference: string mySong(string songlist[], int songnum) { for (i = 0; i < songnum; i++) { output += songlist[i]; output += bone1; ... available answers make sense with what I know about programming so far. So I am looking for the pin point solution to my above C++ related error.
