Thread: unknown error

the code I'm writing does compile, but when I run it through my IDE,
I keep getting this error message:

Executable “multicalc” has exited due to signal 10 (SIGBUS).

Please enter a menu option:

Type 4 for circumferences
Type 5 for equations
Type 6 for vector math
Type 7 for help
Type 8 to quit:

Enter vector 1, hit enter after each element, and end your last element with "L":

Executable “multicalc” has exited due to signal 10 (SIGBUS).

the code I'm using is:

Code:

//vect.h
//does vector math

#include <iostream>
#include <string>
#include <cmath>
#include <cstdlib>
#include <cstring>
#include <vector>
#include <sstream>

using namespace std;
using std::string;

class vect {
public:

	vector <float> vector1;
	vector <float> vector2;
	string vectorsWhole[2];
	vector <string> inread;
	bool last;
	int choice;
	int vectIndex[2];
	char func;
	float scalar;
	vector <float> vectorEQ;
	
	bool lastElement(float num){
	
		if(makeString(num).substr(makeString(num).length()-2,makeString(num).length()-1)=="l"){
		
			return true;
			
		}else{
		
			return false;
			
		}//end if
		
	}//end last element
	
	void vec(){
	
		int i=0;
	
		cout<<"Enter vector 1, hit enter after each element, and end your last element with \"L\":\n";
		
		while(lastElement(atof(inread[i].c_str()))==false){
		
			cin>>inread[i];
			
			i++;
			
		}//end while
		
		for(i=0;i<vector1.size();i++){
		
			cout<<inread[i]<<"\n";
			
		}//end for
		
	}//end vec
	
};//end class

the method vec is being called from the main cpp file

any advice?

I found an error in my code:

I was trying to do a substring on a conversion from a float, but the float was orginially a string, so anythign not numerical in the original string would've been lost, hence an error. I corrected it, and I still comile it perfectly, but I get errors when my IDE trys to run the program

the new code is:

Code:

//vect.h
//does vector math

#include <iostream>
#include <string>
#include <cmath>
#include <cstdlib>
#include <cstring>
#include <vector>
#include <sstream>

using namespace std;
using std::string;

class vect {
public:

	vector <float> vector1;
	vector <float> vector2;
	string vectorsWhole[2];
	vector <string> inread;
	bool last;
	int choice;
	int vectIndex[2];
	char func;
	float scalar;
	vector <float> vectorEQ;
	
	bool lastElement(string num){
	
		if(num.substr(num.length()-2,num.length()-1)=="l"){
		
			return true;
			
		}else{
		
			return false;
			
		}//end if
		
	}//end last element
	
	void vec(){
	
		int i=0;
	
		cout<<"Enter vector 1, hit enter after each element, and end your last element with \"L\":\n";
		
		while(lastElement(inread[i])==false){
		
			cin>>inread[i];
			
			i++;
			
		}//end while
		
		for(i=0;i<vector1.size();i++){
		
			cout<<inread[i]<<"\n";
			
		}//end for
		
	}//end vec
	
};//end class

no, u just didn't read the code

I add someting to inread right here:

Code:

while(lastElement(inread[i])==false){
                
          cin>>inread[i];
                        
          i++;
                        
}//end while

Look again.

You add something to inread right there. Right after you use it in your while expression.

Didn't you get the memo?

OOOHHHHH...

sry, my bad, with the conditions i used I should have put a do while statement instead of a while

oops
