Square (C++)

Square

squareHollow() draws a hollow square and it takes 2 parameters:

noOfLines takes the number of lines.

ch takes the character to be displayed in the hollow square.

squareFilled() draws a filled square and it takes 2 parameters:

noOfLines takes the number of lines.

ch takes the character to be displayed in the filled square.
