Array multiplication problem

[NYCrealist123]

int arr [3] [3] = {{1, 2, 3}, {4, 5, 6}, {7, 8, 9}};

Write a few lines of code (not a separate function) that will find the product of rows 0 and 1 of arr. Print the product.



FYI, the product is 720.

FYI, it's polite to say "please" when issuing orders to strangers on the internet.

Use a variable to hold the product
int prod = 1;
Then put the following in a for loop

prod *= arr[0][i];
prod *= arr[1][i];

You're welcome. Glad that was enough to solve the problem.
