Change Code To Loop

[marsh]

Hello, i am attempting to change this code into a loop. I realized that i coded it very badly. I do not have to keep adding to my linedone if i just reset it to 0 each time.

Either way i am having trouble turning this code into a loop:

stringstream ss(gtile[3]); while (ss >> value && linedone < 20) { ss >> comma; linedone ++; data[linedone] = value; }
stringstream ss1(gtile[4]); while (ss1 >> value && linedone < 40 && linedone > 19) { ss1 >> comma; linedone ++; data[linedone] = value;}
stringstream ss2(gtile[5]); while (ss2 >> value && linedone < 60 && linedone > 39) { ss2 >> comma; linedone ++; data[linedone] = value;}
stringstream ss3(gtile[6]); while (ss3 >> value && linedone < 80 && linedone > 59) { ss3 >> comma; linedone ++; data[linedone] = value;}
stringstream ss4(gtile[7]); while (ss4 >> value && linedone < 100 && linedone > 79) { ss4 >> comma; linedone ++; data[linedone] = value;}
stringstream ss5(gtile[8]); while (ss5 >> value && linedone < 120 && linedone > 99) { ss5 >> comma; linedone ++; data[linedone] = value;}
stringstream ss6(gtile[9]); while (ss6 >> value && linedone < 140 && linedone > 119) { ss6 >> comma; linedone ++; data[linedone] = value;}
stringstream ss7(gtile[10]); while (ss7 >> value && linedone < 160 && linedone > 139) { ss7 >> comma; linedone ++; data[linedone] = value;}
stringstream ss8(gtile[11]); while (ss8 >> value && linedone < 180 && linedone > 159) { ss8 >> comma; linedone ++; data[linedone] = value;}
stringstream ss9(gtile[12]); while (ss9 >> value && linedone < 200 && linedone > 179) { ss9 >> comma; linedone ++; data[linedone] = value;}
stringstream ss10(gtile[13]); while (ss10 >> value && linedone < 220 && linedone > 199) { ss10 >> comma; linedone ++; data[linedone] = value;}
stringstream ss11(gtile[14]); while (ss11 >> value && linedone < 240 && linedone > 219) { ss11 >> comma; linedone ++; data[linedone] = value;}
stringstream ss12(gtile[15]); while (ss12 >> value && linedone < 260 && linedone > 239) { ss12 >> comma; linedone ++; data[linedone] = value;}
stringstream ss13(gtile[16]); while (ss13 >> value && linedone < 280 && linedone > 259) { ss13 >> comma; linedone ++; data[linedone] = value;}
stringstream ss14(gtile[17]); while (ss14 >> value && linedone < 300 && linedone > 279) { ss14 >> comma; linedone ++; data[linedone] = value;}

Here is my attempt, which crashes

while (loopnum < 15)
{
	stringstream ss(gtile[linedone + 3]);
	while (ss >> value)
	{
		ss >> comma;
		linedone ++;
		data[linedone] = value;

	}
	value = 0;
}

Here is a picture of the error

Thanks for any help i may recieve.

Looking at your original code, it appears that your gtile is an array of 15 elements:

stringstream ss(gtile[3]);
stringstream ss1(gtile[4]);
stringstream ss2(gtile[5]);
stringstream ss3(gtile[6]);
stringstream ss4(gtile[7]);
stringstream ss5(gtile[8]);
stringstream ss6(gtile[9]);
stringstream ss7(gtile[10]);
stringstream ss8(gtile[11]);
stringstream ss9(gtile[12]);
stringstream ss10(gtile[13]);
stringstream ss11(gtile[14]);
stringstream ss12(gtile[15]);
stringstream ss13(gtile[16]);
stringstream ss14(gtile[17]);

However, in the while loop, your addressing much more than that:

stringstream ss(gtile[linedone + 3]);

since linedone is continuously incremented and appears that it could reach a value of 299!

Hope that helps.

Thanks for the help.

Got it working with this code

linedone2 = 3;
linedone = 0;
while (linedone < 300)
{
	stringstream ss(gtile[linedone2]);
	while (ss >> value)
	{
		ss >> comma;
		linedone ++;
		data[linedone] = value;

	}
	if (linedone > 14)
	{
	linedone2++;
	}
	value = 0;
}
linedone = 0;
linedone2 = 0;

stringstream ss6(gtile[9]); while (ss6 >> value && linedone < 140 && linedone > 119) 
{ ss6 >> comma; linedone ++; data[linedone] = value;}

Let's try to generalize. If instead of 9 you'd have i, then the code above could look like this:

stringstream ssi(gtile[i+3]); while (ssi >> value && linedone < (i+1)*20 && linedone > i*20-1) 
{ ssi >> comma; linedone ++; data[linedone] = value;}

But you need 15 stringstreams, so

stringstream ss[15];
for(int i = 0; i < 15; ++i)
{
   ss[i] = stringstream(gtile[i+3]);
   while (ssi >> value && linedone < (i+1)*20 && linedone > i*20-1) 
   { ssi >> comma; linedone ++; data[linedone] = value; }
}
