make an algorithm in C language 

Find palindromic words in the matrix lines and print the starting position (row x column) and end position (row x column), and the word found

 Matrix size is user defined - Array values are characters - * = any value - I suggest turning everything into uppercase or lowercase

The language must be implemented in being C and not in C ++

exit : ovo -(0,1)-(0,3)

ArARa(2,0)-(2,4)

ps: the palindrome must be printed along with its position in the character matrix

Exemplo para linhas * Ovo * * * * * ar A Ra * * * * * * * Sada: OVO -(0,1) -(0,3) ArARa (2,0) -(2,4)
