I’m trying to print a full closed maze (where the user inputs width and height), but when I print the maze the "|" walls are not placed correct. Why is this, because the parameters are set. Also the right amount of "|" are placed but at wrong positions
int vectorLength = (userRows * 2) + 1;
int vectorWidth = (userColloms * 4) + 1;
std::vector<std::vector<std::string>> maze(vectorWidth, std::vector<std::string>(vectorLength, ""));
for (unsigned int i = 0; i < vectorLength; i++) {
int testj = 0;
for (unsigned int j = 0; j < vectorWidth; j++) {
if (i % 2 == 0){
if (j == 0 || j == 4 || j == 8 || j == 12 || j == 16 || j == 20 || j == 24 || j == 28 || j == 32) {
maze.at(j).at(i) = "+";
} else {
maze.at(j).at(i) = "-";
}
}
if (i % 2 != 0){
if (j == 0 || j == 4 || j == 8 || j == 12 || j == 16 || j == 20 || j == 24 || j == 28 || j == 32) {
maze.at(j).at(i) = "|";
}
}
}
}
The output for input 3 3 :
+—+—+—+

+—+—+—+
Program ended with exit code: 0
>Solution :
It looks like your code works by replacing characters in your maze vector. Since your vector is initialized all to empty strings, there is nothing between each "|" to give space. You should either initialize your vector to be full of spaces " " or find another way to pad the space between each bar.
