In mathematics, a matrix is a collection of numbers arranged into a fixed number of rows and colums. The numbers arranged in a matrix usually a real numbers. In general, matrices can contain complex numbers as well, but it's rarest one to see. Some examples of matrix format are given below.

Arrays are one of a kind of data structure because arrays defines the way of arranging the data, which allows us to manipulated the data in interesting ways.Array is a collection of data, which is very similar to a matrix but a difference is that array can hold only data of similar datatypes ie) We could have an array of intergers or an array of characters or an array of floating point.

All Arrays are Matrix, but all Matrices or not an Array

Lets code a C program to Sum two array matrices

c-matrices-addition-1.c

#include <stdio.h> int main() { int i , j, row1, col1, a[10][10], b[10][10] ; printf("Enter the order of matrix up to (10 x 10): \n" ); scanf("%d %d " , &row1 , &col1 ); printf( "\nEnter the Elements of matrix A :\n" ); for( i = 0; i < row1; i++ ) { for( j = 0; j < col1; j++ ) { scanf("%d " , &a[i][j] ); } } printf("\nEnter the Elements of matrix B: \n" ); for( i = 0; i < row1; i++ ) { for( j = 0; j < col1; j++ ) { scanf("%d ", &b[i][j] ); } } printf("\nMatrix Addition: \n" ); for( i = 0; i < row1; i++ ) { for( j = 0; j < col1; j++ ) { printf("%4d" , a[i][j] + b[i][j] ); } printf("\n" ); } return 0; }

Enter the order of matrix up to (10 x 10) : 3 3 Enter the Elements of matrix A : 1 1 1 1 1 1 1 1 1 Enter the Elements of matrix B : 1 1 1 1 1 1 1 1 1 Matrix Addition: 2 2 2 2 2 2 2 2 2

Here we used two for loops to collect the values in matrix form for an array a[ ][ ]. Same procedure is repeated to collect the values in matrix form for an array b[ ][ ] Now we used 3rd set of two for loops to display the addition of two matrices without storing a summation values in any temporary array.

Lets code a C program to Sum two array matrices with improved level.

c-matrices-addition-2.c

#include <stdio.h> int main() { int i ,j, k, row1, col1, a[10][10], b[10][10] ; printf("Enter the order of matrix up to (10 x 10): \n" ); scanf("%d %d" , &row1 , &col1 ); for(k = 65;k <= 66;k++) { printf("\nEnter the Elements of matrix %c :\n",k ); for( i = 0; i < row1; i++ ) { for( j = 0; j < col1; j++ ) { if(k == 65) scanf( "%d" , &a[i][j] ); if(k == 66) scanf( "%d" , &b[i][j] ); } } } printf("\nMatrix Addition: \n" ); for( i = 0; i < row1; i++ ) { for( j = 0; j < col1; j++ ) { printf("%4d" , a[i][j] + b[i][j] ); } printf("\n" ); } return 0; }

Here we used single for loops to collect the values in matrix form for an arrays a[ ][ ] and b[ ][ ]. Now we used 2nd set of two for loops to display the addition of two matrices without storing a summation values in any temporary array.

We may make mistakes(spelling, program bug, typing mistake and etc.), So we have this container to collect mistakes. We highly respect your findings.
