Posted By: Adalbert Fischer     Category: C Programming     Views: 8186

WRITE A PROGRAM CONTAINING A USER DEFINED FUNCTION
USING POINTER TO ADD TWO MATRICES TO RETURN THE
RESULTANT MATRIX TO THE CALLING FUNCTION.

Code for Program to add to matrices using pointers in C Programming

#include <stdio.h>
#include <conio.h>

main()
{
    int *m1=0,*m2=0,*m3,i,j;
    int row,col;
    int * add(int *m1,int *m2,int row,int col);
    row=col=3;
    clrscr();
    printf("\nENTER VALUE FOR THE FIRST ARRAY:->");
    m1=(int*) malloc(sizeof(int)*row*col);
    for(i=0;i<row;i++)
    {
        for(j=0;j<col;j++)
        {
            scanf("%d",m1+i*col+j);
        }
    }
    printf("\nENTER VALUE FOR THE SECOND ARRAY:->");
    m2=(int*) malloc(sizeof(int)*row*col);
    for(i=0;i<row;i++)
    {
        for(j=0;j<col;j++)
        {
            scanf("%d",m2+i*col+j);
        }
    }
    m3=(int*) malloc(sizeof(int)*row*col);
    m3=add(m1,m2,row,col);
    printf("THE RESULT IS :->");
    for(i=0;i<row;i++)
    {
        for(j=0;j<col;j++)
        {
            printf("%d ",*(m3+i*col+j));
        }
    }

}

int * add(int *m1,int *m2,int row,int col)
{
    int *m3=(int*) malloc(sizeof(int)*row*col);
    int i,j,k,a1;
    for(i=0;i<row;i++)
    {
        for(j=0;j<col;j++)
        {
            a1=*(m1+i*col+j)+*(m2+i*col+j);
            *(m3+i*col+j)=a1;
        }
    }
    return m3;
}
