Question

I am trying to read a sentence from a text file and store it in a 2D array. I am using the function cin.getline. I am trying to store each sentence of the text file to a row of the 2D array.read is my ifstream object. Below is a sample of my code

for (int i = 0; i < 7; i++)
{
    int k=0;
    read.getline(people.wishlist[i][k], MAX); // store in row 0 when i is 0
}

// what my text file looks like: 

// Hey how is your day
// whats up

The error message I am getting:

error C2664: 'std::basic_istream<_Elem,_Traits> &std::basic_istream<_Elem,_Traits>::getline(_Elem *,std::streamsize)':
cannot convert parameter 1 from 'char' to 'char *'

Can someone suggest a good method to solve this problem for me? Thanks

Answer 1

The problem is that on a 2D char array people.wishlist[i][k] stands for a single char (ith row and kth column), but getline expects a string of them char*.

You need a pointer to a 1D char array, which you can get indexing just one other dimension. (with i) You could try it this way:

read.getline(people.wishlist[i], MAX);
