**Pascal Program For Matrix Multiplication:**This is a Pascal program to Multiply arrays A[i , j] and B[i, j].

Each element of the resulting matrix is multiplied by 1/4, and the result is displayed in a new Array.

### What is an Array?

An array consists of rows and columns, and in programming, it is a data type used to hold a range of data of the same type.

The same data type here could be integer, string, Boolean, or real.

### Logic of The Program

The Arrays used in this computation have two rows and two columns respectively, hence the resulting matrix or array must also be a 2 x 2 matrix.

First, the two arrays are multiplied together, where a row is used to multiply a column.

After their multiplication which is given to a new Array C, the result in Array C is multiplied by 1/4 to give the final matrix D whose result is displayed as an output to the user.

As with most looping Pascal Programs, here we've implemented the FOR DO control statement, which ensures that we're working with a 2 x 2 Matrix.

The FOR DO structure in Pascal Programming is given by:

FOR variable:= startvalue TO endvalue Do

Statement(s)

### Program Code

Program begn;

Var

A, B, C, D : Array [1..2,1..2] of real;

I, j: integer;

Var

A, B, C, D : Array [1..2,1..2] of real;

I, j: integer;

Begin

For i:= 1 to 2 do

For j:= 1 to 2 do

Begin

Readln (A[i, j]);

End;

Begin

For i:= 1 to 2 do

For j:= 1 to 2 do

Readln (B[i, j]);

End;

Begin

For i:= 1 to 2 do

For j:= 1 to 2 do

C[i, j]:= A[i, j] * B[i, j];

End;

For i:= 1 to 2 do

For j:= 1 to 2 do

Begin

Readln (A[i, j]);

End;

Begin

For i:= 1 to 2 do

For j:= 1 to 2 do

Readln (B[i, j]);

End;

Begin

For i:= 1 to 2 do

For j:= 1 to 2 do

C[i, j]:= A[i, j] * B[i, j];

End;

Begin

For i:= 1 to 2 do

For j:= 1 to 2 do

D[i, j]:= 1/4 * C[i, j];

End;

Begin

For i:= 1 to 2 do

For j:= 1 to 2 do

Writeln (D[i, j]);

Readln;

End;

End.

For i:= 1 to 2 do

For j:= 1 to 2 do

D[i, j]:= 1/4 * C[i, j];

End;

Begin

For i:= 1 to 2 do

For j:= 1 to 2 do

Writeln (D[i, j]);

Readln;

End;

End.
