Hello guys
I am a student of Computer Technology. I am studying C/C++ and very soon will start Java. Its really hard to study three language at a time. But there is no way to avoid this ! Because I have to study C/C++ and Java at a time to cut a good figure at exam. Beside its really fun to learn programming ! I always enjoy programming.
I have just come here at CodeClerks forum and thought that I can learn new programming logic here and also can share some of my programs. I hope you guys will also share your programming knowledge with me. ;)
Recently I have just wrote a program for Multiplying two Matrix. I believe that we can solve a problem with several algorithms. So I thought I should share my code here and hope you will also share your code with me. Then we will be able to learn different algorithms
#include <stdio.h>
int main
(){ int m
, n
, p
, q
, c
, d
, k
, sum
= 0; int first_matrix
[10][10], second_matrix
[10][10], multiply
[10][10]; printf("Enter the number of rows and columns of first matrix\n"); scanf
("%d%d", &m
, &n
); printf("Enter the elements of first matrix\n"); for (c
= 0; c
< m
; c
++) for (d
= 0; d
< n
; d
++) scanf
("%d", &first_matrix
[c
][d
]); printf("Enter the number of rows and columns of second matrix\n"); scanf
("%d%d", &p
, &q
); if (n
!= p
) printf("Matrices with entered orders can't be multiplied with each other.\n"); else { printf("Enter the elements of second matrix\n"); for (c
= 0; c
< p
; c
++) for (d
= 0; d
< q
; d
++) scanf
("%d", &second_matrix
[c
][d
]); for (c
= 0; c
< m
; c
++) { for (d
= 0; d
< q
; d
++) { for (k
= 0; k
< p
; k
++) { sum
= sum
+ first_matrix
[c
][k
]*second_matrix
[k
][d
]; } multiply
[c
][d
] = sum
; sum
= 0; } } printf("Product of entered matrices:-\n"); for (c
= 0; c
< m
; c
++) { for (d
= 0; d
< q
; d
++) printf("%d\t", multiply
[c
][d
]); printf("\n"); } } return 0;}
Now, tell me about your algorithm of matrix multiply. Can we do this with one dimensional/linear array ??
