matrix multiplication program in c

program for multiplication of two matrices:

#include<stdio.h>
#define ROW1 3
#define COL1 4
#define ROW2 COL1
#define COL2 2
int main(void)
{
int mat1[ROW1][COL1],mat2[ROW2][COL2],mat3[ROW1][COL2];
int i,j,k;
printf("Enter matrix mat1(%dx%d)row-wise :\n",ROW1,COL1);
for(i=0; i<ROW1; i++)
for(j=0; j<COL1; j++)
scanf("%d",&mat1[i][j]);
printf("Enter matrix mat2(%dx%d)row-wise :\n",ROW2,COL2);
for(i=0; i<ROW2; i++)
for(j=0; j<COL2; j++)
scanf("%d",&mat2[i][j] );
/*Multiplication*/
for(i=0; i<ROW1; i++)
for(j=0; j<COL2; j++)
{
mat3[i][j] = 0;
for(k=0; k<COL1; k++)
mat3[i][j] += mat1[i][k] * mat2[k][j];
}
printf("The Resultant matrix mat3 is :\n");
for(i=0; i<ROW1; i++)
{
for(j=0; j<COL2; j++)
printf("%5d",mat3[i][j]);
printf("\n");
}
return 0;
}
