# C Program to Implement Matrix Multiplication

This C Program Implements Matrix Multiplication,Given Two Matrices as Input,it Checks whether multiplication is possible by checking column of matrix 1 is equal to row of matrix 2,then proceeds by multiplying matrices

```
#include
int main()
{
int m, n, p, q, c, d, k, sum = 0;
int first[10][10], second[10][10], multiply[10][10];
printf("Enter the number of rows and columns of first matrixn");
scanf("%d%d", &m, &n);
printf("Enter the elements of first matrixn");
for ( c = 0 ; c < m ; c++ )
for ( d = 0 ; d < n ; d++ )
scanf("%d", &first[c][d]);
printf("Enter the number of rows and columns of second matrixn");
scanf("%d%d", &p, &q);
if ( n != p )
printf("Matrices with entered orders can't be multiplied with each other.n");
else
{
printf("Enter the elements of second matrixn");
for ( c = 0 ; c < p ; c++ )
for ( d = 0 ; d < q ; d++ )
scanf("%d", &second[c][d]);
for ( c = 0 ; c < m ; c++ )
{
for ( d = 0 ; d < q ; d++ )
{
for ( k = 0 ; k < p ; k++ )
{
sum = sum + first[c][k]*second[k][d];
}
multiply[c][d] = sum;
sum = 0;
}
}
printf("Product of entered matrices:-n");
for ( c = 0 ; c < m ; c++ )
{
for ( d = 0 ; d < q ; d++ )
printf("%dt", multiply[c][d]);
printf("n");
}
}
return 0;
}
```

OUTPUT
