hi every one...........

i'm new in this forum and need ur help please....

i want to write a programme using c++ code,

programme that find the optimal parenthesization of a matrix-chain product, then perform the optimal matrix -chain multiply 4 a sequence of matrices, but the user should enter the number of the matrices and its dimensions.........

plz need ur help guys

thnx .........

Try reading this:-

>then perform the optimal matrix -chain multiply 4 a sequence of matrices

Multiplication would go something like this:-

```
public static void mmult (int rows, int cols,
int[][] m1, int[][] m2, int[][] m3) {
for (int i=0; i<rows; i++) {
for (int j=0; j<cols; j++) {
int val = 0;
for (int k=0; k<cols; k++) {
val += m1[i][k] * m2[k][j];
}
m3[i][j] = val;
}
}
}
```

>but the user should enter the number of the matrices and its dimensions.........

I assume you know what **cin** is and how to initialise a 2D array?

Given an array of 10 elements, sort the data from index 2 to 6 using insertion sort algorithm.

Write the c/c++ code for Matrix Chain Multiplication Algorithm for at least 5 matrixes.

please solve this in c code.
