Programm to find adjoint of a matrix.

the user can input a double dimension array and we have to display the matrix...as well as find its adjoint. can anyone post any algorithm to do so...

Displaying the matrix should be easy with two nested for loops iterating over rows and columns, just include spaces for proper formatting. If runtime is not a concern, you can write a simple recursive function to calculate the determinant and use that to get the input matrix's (n-1)x(n-1) minors, which are the entries of the classic adjoint. There is a lot to be optimised here, as for example you are computing several minors more than once. If you want an optimal solution, you should probably pick up a book on computer algebra.
