#### Program or Solution

``` #include <stdio.h> int main() { int r1, c1, r2, c2, i, j, k; printf("Enter rows and column for first matrix: "); scanf("%d %d", &r1, &c1); printf("\nEnter rows and column for second matrix: "); scanf("%d %d",&r2, &c2); if (c1 != r2) { printf("\ncolumn of first matrix not equal to row of second.\n"); } else { int a[r1][c1],b[r2][c2],result[r1][c2]; printf("\nEnter elements of matrix 1:\n"); for(i=0; i<r1; ++i) for(j=0; j<c1; ++j) { scanf("%d", &a[i][j]); } printf("\nEnter elements of matrix 2:\n"); for(i=0; i<r2; ++i) for(j=0; j<c2; ++j) { scanf("%d",&b[i][j]); } for(i=0; i<r1; ++i) for(j=0; j<c2; ++j) { result[i][j] = 0; } for(i=0; i<r1; ++i) for(j=0; j<c2; ++j) for(k=0; k<c1; ++k) { result[i][j]+=a[i][k]*b[k][j]; } printf("\nOutput Matrix:\n"); for(i=0; i<r1; ++i) for(j=0; j<c2; ++j) { printf("%d ", result[i][j]); if(j == c2-1) printf("\n\n"); } } return 0; } ```
