Question

using c language:

create functions that perform the following actions on 2 dimensional arrays (matrices), write these functions using pointers only (do not use []). Write a function that computes the addition of two arbitrary but same sized matrices. Write a function that computes the matrix determinant. The number of matrix rows and columns must be the same but the function should give the correct answer for any size square matrix.

Answer 1

#include<stdio.h>
void main()
{
int a[10][10],b[10][10],c[10][10],i,j,m,n;
printf("Enter m & n:");
scanf("%d %d",&m,&n);
printf("Enter 1 matrix:");
for(i=0;i<m;i++)
{
for(j=0;j<n;j++)
{
scanf("%d",(*(a+i)+j));
}
}
printf("\nEnter 2 matrix:");
for(i=0;i<m;i++)
{
for(j=0;j<n;j++)
{
scanf("%d",(*(b+i)+j));
}
}
printf("\nAddition Matrix:\n");
for(i=0;i<m;i++)
{ for(j=0;j<n;j++)
{
*(*(c+i)+j)=*(*(a+i)+j)+ *(*(b+i)+j);
printf("%d ",*(*(c+i)+j));
}
printf("\n");
}
}

Output:
