1: Write a NumPy program to create a 3x3 matrix with values ranging from 2 to 10. Expected Output: [[ 2 3 4] [ 5 6 7] [ 8 9 10]] 2: Write a NumPy program to convert an array to a float type. Sample output: Original array [1, 2, 3, 4] Array converted to a float type: [ 1. 2. 3. 4.] 3: Following is the provided numPy array. return array of items in the third column from all rows. sampleArray = numpy.array([[11,22, 33], [44, 55, 66], [77, 88, 99]])

Qn 1: Write a C++ program to multiply 2 matrices using multi-dimensional arrays. Program should ask the user to input the values of both matrices(arrays). Example: Input Input first matrix 2 4 1 2 3 9 Input second matrix 1 2 3 3 6 1 2 9 7 Output Product of the 2 matrices is 16 37 17 29 103 72

Write a function that calculates the totals of the rows in a 2D array with 5 columns.  Store the row totals into a separate 1D array.  Pass both arrays into the function along with the number of rows in the 2D array.
