How do you write a C program to find the adjoint of a matrix?
To write a C program to find the adjoint of a matrix, first, you need to create a function to calculate the cofactor of each element in the matrix. Then, construct the adjoint by transposing the cofactor matrix. The program should read the matrix size and elements from user input, compute the cofactors using nested loops, and finally display the adjoint matrix by transposing the cofactor matrix. Make sure to handle memory allocation for dynamic matrices if needed.
