C program for matrix multiplication of two matrix

Hello everybody I want to discuss the source code for matrix multiplication in c programming.

Program Code


//C program for multiplication of two matrix
#include < stdio.h >
#include < conio.h >
void main()
{
 int a[3][3], b[3][3], c[3][3], i, j, k;
 clrscr();
 printf("Enter the elements of first 3x3 matrix");
 for (i = 0;i < 3; i++)
 {
  for (j = 0; j < 3; j++)
  {
   scanf("%d",&a[i][j]);
  }
 }
 printf("\nEnter the elements of second 3x3 matrix");
 for(i = 0; i < 3; i++)
 {
  for (j = 0; j < 3; j++)
  {
   scanf("%d", &b[i][j]);
  }
 }
 printf("\nThe first matrix is :-\n");
 for (i = 0; i < 3; i++)
 {
  for (j = 0; j < 3; j++)
  {
   printf("\t%d", a[i][j]);
  }
  printf("\n");
 }
 printf("\nThe second matrix is :-\n");
 for (i = 0; i < 3; i++)
 {
  for (j = 0; j < 3; j++)
  {
   printf("\t%d", b[i][j]);
  }
  printf("\n");
 }

 printf("\nMultiplication of the two matrices is as follows:\n");
 for (i = 0;i < 3; i++)
 {
  printf("\n");
  for (j = 0; j < 3; j++)
  {
   c[i][j]=0;
   for(k=0;k<3;k++)
   c[i][j] = c[i][j]+a[i][k] * b[k][j];
   printf("\t%d", c[i][j]);
  }
 }
 getch();
}

Input :

Enter the elements of first 3x3 matrix

for(i=0;i < 3;i++)
{
for(j=0;j < 3;j++)
{
scanf("%d",&arr[i][j]);
}
}
printf("Original array entered by the user is \n");
for(i=0;i < 3;i++)
{
for(j=0;j < 3;j++)
{
printf("%d ",arr[i][j]);
}
printf("\n");
}
printf("\n Transpose of the array is \n");
for(i=0;i < 3;i++)
{
for(j=0;j < 3;j++)
