In the C printf: fprintf(outfile, "%4.2f%d\n", omega, iter_no ); The corresponding solution or error messages are to be printed as the following: • Each entry of the solution is to be printed as in the C fprintf: fprintf(outfile, "%12.8f\n", x ); • If the matrix A has a zero column, print the message “Matrixhas azerocolumn.Nouniquesolutionexists.\n”. • If the method fails to give a solution after N iterations, print the message “Maximumnumberofiterationsexceeded.\n”. • If there is an entry of that is out of the range [ −2 127 , 2 127 ], print the message “Noconvergence.\n”.
