How do you write a c program to add two matrices using functions?

Answer 1

#include<stdio.h>

#include<conio.h>

#include<process.h>

void read_matrix(int x[10][10],int r,int c)

{

int i,j;

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

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

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

}

void print_matrix(int x[10][10],int r,int c)

{

int i,j;

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

{

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

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

printf("\n");

}

}

void add_matrix(int x[10][10],int y[10][10],int z[10][10],int r,int c)

{

int i,j;

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

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

z[i][j]=x[i][j]+y[i][j];

}

void main()

{

int a[10][10],b[10][10],c[10][10],ra,ca,rb,cb;

clrscr();

printf("Enter order of 2 matrices");

scanf("dd",&ra,&ca,&rb,&cb);

if(ra!=rbca!=cb)

{

printf("addition is not possible");

exit(0);

}

printf("Enter A\n");

printf("Enter B\n");

read_matrix(a,ra,ca);

read_matrix(b,rb,cb);

add_matrix(a,b,c,ra,ca);

print_matrix(c,ra,ca);

getch();

}
