int a[5][5],b[5][5],row,col;

void add(int(*)[5]);

int main()
{
    int c[5][5],i,j;

    scanf("%d",&col);
    printf("Enter matrix A :\n");
    for(i=0;i<row;i++)
    {
        for(j=0;j<col;j++)
        {

why is this not working ?


#include<stdio.h>
#include<conio.h>
int * accept(int *a,int r,int c)
{
int i,j;
for(i=0;i<r;i++)
for(j=0;j<c;j++)
scanf("%d",a[i][j]);
return a;
}

int *add(int *a,int *b,int r,int c)
{
int i,j,*d;
for(i=0;i<r;i++)
for(j=0;j<c;j++)
d[i][j]=a[i][j]+b[i][j];
return d;
}

int main()
{
int *p,*p1,*p3;
p=accept(p,2,2);
p1=accept(p1,2,2);
p3=add(p,p1,2,2);
for(i=0;i<2;i++)
{
for(j=0;j<2;j++)
{
printf("%d ",p3[i][j]);
}
printf("\n");
}
return 0;
}
