C Program To Add Two Matrices Using Function

 How to add 2 matrix in c

Algorithm for adding 2 matrices

1) Check the sizes of two matrices math A (m×n) and math B (u X v): if m = u and n = u then display a message matrix addition is possible . Otherwise print matrix not possible Exit .

2) Create a new square matrix of size m×n.

3) For each element in A find the element at the same position at B and add the two values.

Main variables

m1,m2 = 2 matrices 2d arrays

n = Result matrix

i,j = Loop controllers

r,r1,c,c1 = Row and Column

Program

#include<stdio.h>

main()

{

int i,j,r,c,r1,c1,m1[50][50],m2[50][50],n[50][50];

void matsum(int[50][50],int,int);

printf("Enter the number of rows and column of 1st matrix\n");

scanf("%d %d",&r,&c);

printf("Enter the elements of matrix 1");

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

{

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

{

scanf("%d",&m1[i][j]);

}

}

printf("Enter the number of rows and column of 2nd matrix\n");

scanf("%d %d",&r1,&c1);

printf("Enter the elements of matrix 2");

for(i=0;i<r1;i++)

{

for(j=0;j<c1;j++)

{

scanf("%d",&m2[i][j]);

}

}

if((r1==r)&&(c1==c))

{

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

for(j=0;j<c1;j++)

{

n[i][j]=0;

n[i][j]=m1[i][j]+m2[i][j];

}

matsum(n,r,c1);

}

else

printf("Matrix addition not possible\n");

}

void matsum(int x[50][50],int y,int z)

{

int i,j;

printf("Sum of the matrices is \n");

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

{

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

{

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

printf("\t");

}

printf("\n");

}}

Output

Enter the number of rows and column of 1st matrix

2 2

Enter the elements of matrix

1 1

1 1

Enter the number of rows and column of 2nd matrix

2 2

Enter the elements of matrix

2 2
