ADDITION OF TWO MATRICES USING C PROGRAM

---

---

C program for addition of two matrices using arrays source code. Matrix addition in c language:

C code:

#include<stdio.h>

int main(){

  int a[3][3],b[3][3],c[3][3],i,j;

  printf("Enter the First matrix->");

  for(i=0;i<3;i++)

      for(j=0;j<3;j++)

           scanf("%d",&a[i][j]);

  printf("\nEnter the Second matrix->");

  for(i=0;i<3;i++)

      for(j=0;j<3;j++)

           scanf("%d",&b[i][j]);

  printf("\nThe First matrix is\n");

  for(i=0;i<3;i++){

      printf("\n");

      for(j=0;j<3;j++)

           printf("%d\t",a[i][j]);

  }

  printf("\nThe Second matrix is\n");

  for(i=0;i<3;i++){

      printf("\n");

      for(j=0;j<3;j++)

      printf("%d\t",b[i][j]);

   }

   for(i=0;i<3;i++)

       for(j=0;j<3;j++)

            c[i][j]=a[i][j]+b[i][j];

   printf("\nThe Addition of two matrix is\n");

   for(i=0;i<3;i++){

       printf("\n");

       for(j=0;j<3;j++)

            printf("%d\t",c[i][j]);

   }

   return 0;

}

Algorithm:

Addition of two matrices:

Rule: Addition of two matrices is only possible if both matrices are of same size.

Suppose two matrices A and B is of same size m X n

Sum of two matrices is defined as

(A + B)_ij  = A_ij + B_ij

Where 1 ≤ i ≤ m and 1 ≤ j ≤ n

For example:

Suppose two matrices A and B of size of 2 X 3 is as follow:
