Okay, so I am a bit stuck. I am trying to ask the user to enter 16 characters and output their input into a grid. However, I keep running into an error:

Error: cannot convert 'std::__cxx11::string aka std::__cxx11::basic_string<char>' to 'char' in assignment.

I don't understand what the error is and I did my best to try and figure out the issue but not working.

For example:

1. User enters 1234123412341234


2. It should output:

1 2 3 4

1 2 3 4

1 2 3 4

1 2 3 4

Here is the code:

#include <iostream>
#include <stdlib.h>

using namespace std;

void fillLgArray(char grid[LG_GRID], int direction);

void outputLgArray(char grid[LG_GRID]);


int main()

 char myGrid1[LG_GRID][LG_GRID];
 doCommand (myGrid1);

 return 0;



void fillLgArray(char grid[LG_GRID], int direction)

 string userInput;

 cout << "Please enter 16 characters!n";
 cin >> userInput;

 if(userInput.length() > 16)

 userInput = userInput.substr(0, 16);
 

 cout << "You entered " << userInput << endl;

 if (direction = 1)
 for (int row = 0; row < LG_GRID; row++)
 for (int col = 0; row < LG_GRID; row++)
 grid [row][col] = userInput;
 
 
 


void outputLgArray(char grid[LG_GRID])

 for (int row=0;row <LG_GRID;row++)
 for(int col=0;col <LG_GRID;col++)
 cout << grid[row][col]<<" ";
 
 cout << endl;
 

grid [row][col] = userInput;

You are trying to assign the whole userInput (which has type std::string aka std::__cxx11::basic_string and is multiple characters long) to a single character grid[row][col] (which is of type char). Specify which character of the string you want to save in the grid[row][col]:

grid [row][col] = userInput[...];

Replace ... by the character index you want to choose.

Not related to question:

for (int col = 0; row < LG_GRID; row++){

row should be col in both cases, otherwise you are not ever actually changing col.
