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  = Aij + Bij
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:
