C++ table input

chris85

Hi was on here last week about a small problem, immback again for another little bit of help.

Im doing a number of successive iterations of a solution through C++ and i want to output the results in a table. I need three columns and the number of rows should will depend on the solution. (ie. there may be more iterations for different solutions so i want the number of rows to be the same as the number of iterations carried out)

I have tried the help menu but am a bit confused, basic user here.

More rows -> Add to an Array?

Can you be more specific? - bit confusing

A 2 dimensional array?

An array that has rows and columns.

int arrayName[numRows][numColumns];

For your solution you should assign numColumns to 3 and make it a constant.

const int NUMCOLUMNS = 3;


Then use nested for loops to iterate through each cell.

for(int i = 0;i < numRows;i++) //iterate through each row
{
 for(int j = 0;j<NUMCOLUMNS;j++)// iterate through each column
 {
cout<<arrayName[i][j]<<"  "; // print the data in the current cell followed by a space
}
cout<<endl;// print a new line and move onto the next row

I think that is what you are asking for, I'm not too sure. There is a guide to 2d arrays here
