Write a program to multiply any two 3 x 3 matrices
Write a program to obtain transpose of a 4 x 4 matrix. The transpose of a matrix is
obtained by exchanging the elements of each row with the elements of the corresponding
column.

column.
Use matrix subtraction to calculate how much longer was the life expectancy of black
and white women than men of the same races in each decade from year 1950 to year
2000. There is no need to store the year data in your matrices—just provide the years in
the output.
a) Input each matrix from user
b) Calculate the matrix difference by calling a function you write called matrix_diff that
will subtract any two 6-by-2 matrices, producing a third 6-by-2 matrix.
c) Display all three matrices with appropriate labels. Your function should calculate the
matrix difference by subtracting each element of the second matrix from the
corresponding element of the first.

Q1. Create a struct called Invoice that a hardware store might use to represent an invoice
for an item sold at the store. An Invoice should include four data members—a part
number (type string), a part description (type string), a quantity of the item being
purchased (type int) and a price per item (type float). Your program should initialize the
four data members. In addition, it should calculate the invoice amount (i.e., multiplies the
quantity by the price per item), If the quantity is not positive, it should be set to 0. If the
price per item is not positive, it should be set to 0. Write a test program that demonstrates
struct Invoice’s capabilities.
Note: Perform this work using
1. 2d array
2. pointer to 2d arrays
3. design function for calculating the results by passing array to function by value and by
reference.

use a one dimensional array to solve the following problem. read in 20 numbers, each of which is between 10 and 100 inclusively. as each number is read, print it only if its not a duplicate of a number already read. provide for the worst case scenario in which all 20 numbers are different . use the smallest possible array to solve this problem.
