**Statement of C Program:**This Program accepts two Matrices of different or same order and Find the product of these Matrices and prints the Product Matrix:

**Condition:**The Column of First Matrix must be Equal to the Row of the Second Matrix.

#include<stdio.h>

#include<conio.h>

void main()

{

int Matrix A[9][9] , MatrixB[9][9] , Matrixsproduct [9][9] ;

int n , i , j , k; /*

**'i' used for rows and 'j' used for columns***/int Row1 , Row2 , Column1 , Column2;

clrscr();

printf(" Enter the order of Matrix A\n");scanf("%d * %d " , &Row1 , &Column1);

printf(" Enter the order of Matrix B\n");

scanf("%d * %d " , &Row2 , &Column2);

**if**(Column1 == Row2)

{

**printf(" Enter the elements of Matrix A\n");**

for(i=0 ; i<Row1 ; i++)

{

for(j=0 ; j<Column1 ; j++)

{

scanf("%d" , &Matrix A[i][j] );

}

}

**printf(" Enter the elements of Matrix B\n");**

for(i=0 ; i<Row2 ; i++)

{

for(j=0 ; j<Column2 ; j++)

{

scanf("%d" , &Matrix B[i][j] );

}

}

**/* Product of two Matrices */**

for(i=0 ; i<Row1 ; i++)

{

for(j=0 ; j<Column2 ; j++)

{

Matrixproduct[i][j] = 0 ;

for(k=0 ; k<Row2 ; k++)

{

Matrixproduct[i][j] = Matrixproduct[i][j] + ( Matrix A[i][k] * Matrix B[k][j] );

}

}

}

**printf(" Product Matrix\n");**

for(i=0 ; i< Row1 ; i++)

{

for(j=0 ;j< Column2;j++)

{

printf("%d" , Matrixproduct[i][j] );

}

printf("\n");

}

} /*

**End of if***/**else**

{

printf(" Invalid order so Multiplication not possible\n");

} /*

**End of main()***/ Output:

Enter the order of Matrix A

2 * 2

Enter the order of MatrixB

2 * 2

Enter the elements of Matrix A

1

2

3

4

Enter the elements of Matrix B

5

43 50

**That's All**

Appreciation for nice Updates, I found something new and folks can get useful info about BEST ONLINE TRAINING

ReplyDeletewhat is the k loop doing there.

ReplyDeleteThe "k" loop is used for to multiple the two matrix and print the sum of the two matrix.

DeleteIts showing error program

ReplyDeletethat's too long ! program.

ReplyDeleteIs there any other logic for multiplication. This logic is somewhat comfusing.

ReplyDeletedo '*' symbol is allowed in scanf() function ?

ReplyDeletefor best explanation visit cncreate.blogspot.in/2014/05/c-programming-language-multiplication.html

ReplyDeleteIts a nice post and sudipta its not at all too long. The logic of the program is in */Product of Two Matrices /* which is quite small..
