cannot append to vector of vectors from another vector

[poopcupine]

Hi, I have a csv file that I have read into a string vector. I also have another integer vector of vectors that set initial values to 0.

I am suppose to check if the value in each vectors of vector are 0, if its 0 then I need to insert the values i gotten from my csv file into the vectors of vector. However, I can only insert to the first vector, 203 is suppose to be in the second vector replacing the first 0.

Any help is appreciated, I am new to C++..

Here are my codes:

<

#include <iostream>
#include <string>
#include <vector>
#include <fstream>
#include <sstream>
#include <iomanip>
using namespace std;
using vec = vector<string>;
using matrix = vector<vec>;

int main() {
	int diskBlocks;
	int entriesPerBlock;
	cout << "Enter number of disk blocks: ";
	cin >> diskBlocks;
	entriesPerBlock = 128 / diskBlocks;
	cout << "Number of entries per block: " << entriesPerBlock << endl;

	/*PART 1*/
	//Creates a vector containing <diskBlock> vectors of int, each containing <entriesPerBlock> ints
	vector<vector<int>> myvecs(diskBlocks, vector<int>(entriesPerBlock));

	//Prints all contents in all vectors in myvecs
	for (const vector<int> &v : myvecs) {
		for (int x : v) cout << x << ' ';
		cout << endl;
	}

	/*PART 2*/
	//Read from csv files and store into vector named 'list'
	vector<vector<string>> list;
	ifstream file("test.csv");
	while (file) {
		string line;
		if (!getline(file, line)) break;

		istringstream ss(line);
		vector<string> words;

		while (ss) {
			string s;
			if (!getline(ss, s, ',')) break;
			words.push_back(s);
		}
		list.push_back(words);
	}
	int j;
	int dataLen = 0;

	for (int i = 0; i < list.size(); i++) {
		for (j = 2; j < list[i].size(); j++) {
			//For adding of files
			if (list[i][0] == "add") {
				dataLen = list[i].size() - 2; //size of data
				//cout << dataLen << endl;
				//cout << list[i][j] << endl;
				//cout << "Adding file" << list[i][1] << endl;
				int toInteger = stoi(list[i][j]);
				cout << toInteger << endl;
				for (int y = 0; y < diskBlocks; y++) {
					for (int x = 0; x < myvecs[i].size(); x++) {
						if (myvecs[y][x] == 0) {
							myvecs[y][x] = toInteger; 
							break;
						}
						else {
							continue;
						} 

					} break;
				}
			}
		}
	}

	cout << "**************************************************************DISK BLOCKS TABLE*************************************************************************" << endl;
	
	//Prints all contents in all vectors in myvecs
	for (const vector<int> &v : myvecs) {
		for (int x : v) cout << x << ' ';
		cout << endl;
	}


	cout << "**************************************************************TEST*************************************************************************" << endl;
	string lol = "0";
	int shit = stoi(lol);
	cout << shit;

my csv file:

add, 100, 101, 102, 103, 104, 105, 106
add, 200, 201, 202, 203
read, 106
delete, 200

my current output is :

101 102 103 104 105 106 201 202
0 0 0 0 0 0 0 0 
0 0 0 0 0 0 0 0 
0 0 0 0 0 0 0 0 
0 0 0 0 0 0 0 0 
0 0 0 0 0 0 0 0 
0 0 0 0 0 0 0 0 
0 0 0 0 0 0 0 0 
0 0 0 0 0 0 0 0 
0 0 0 0 0 0 0 0 
0 0 0 0 0 0 0 0 
0 0 0 0 0 0 0 0 
0 0 0 0 0 0 0 0 
0 0 0 0 0 0 0 0 
0 0 0 0 0 0 0 0 

and my expected output is :

101 102 103 104 105 106 201 202
203 0 0 0 0 0 0 0 
0 0 0 0 0 0 0 0

0 0 0 0 0 0 0 0 
0 0 0 0 0 0 0 0 
0 0 0 0 0 0 0 0

				for (int y = 0; y < diskBlocks; y++) {
					for (int x = 0; x < myvecs[i].size(); x++) {
						if (myvecs[y][x] == 0) {
							myvecs[y][x] = toInteger; 
							break;
						}
						else { //does nothing
							continue;
						} 

					} break; //unconditional break
				}

the outer loop only executes one time
as a suggestion, remove the loops and simply keep track of he index where you are at

y = x = 0; //before line 49
if (list[i][0] == "add"){
   myvecs[y][x] = toInteger;
   ++x;
   if(x==myvecs[y].size()){
      ++y;
      x = 0;
   }
}
