Use the Eigen library to find the inverse of matrices. It is simpler and more efficient than trying to write your own. The only reason to write your own is when you have a better, more efficient method than those that already exist.
A c program is also known as a computer program. A singular matrix has no inverse. An equation to determine this would be a/c=f. <<>> The determinant of a singular matix is zero.
Automated proofs are a complicated subject. If you are not an expert on the subject, all you can hope for is to write a program where you can input a sample matrix (or that randomly generates one), and verifies the proposition for this particular case. If the proposition is confirmed in several cases, this makes the proposition plausible, but is by no means a formal proof.Better try to prove it without writing any program.Note: it is not even true; it is the inverse of the matrix which gives identity when is multiplied with the original matrix.
Write a program in c++ that take input in a integer matrix of size 4*4 and find out if the entered matrix is diagonal or not.
You basically write a nested for loop (one for within another one), to copy the elements of the matrix to a new matrix.
This is a directive, not a question.

A C program to square matrix is a math problem. In the math problem you write down all the outer boundary values of matrix in a circle, then write down the inner value.
Yes, do write. That's what you always have to do when you have got a homework-program.
You basically write a nested for loop (one for within another one), to copy the elements of the matrix to a new matrix.
