Re: [c-prog] its a 2D array problem

[Tyler Littlefield]

first I'm not quite sure what your doing with a==a, b==b, etc. You don't get 
input, and the first if statement will always be true.
You need to get the input, then use a switch statement to find out what they 
typed, use a default label to print an error message.
Second, you do rows,columns. It goes column row, if your working on a grid. 
columns run up and down, while rows run right-to-left
So if you do [row][column] it is reversed.

  this is my program about a 2D array. It should show the output MENU with the 
following choices: A.INSERT B.PRINT C. SEARCH D. EXIT.
  it still got errors.
  main()
  {
  int array[10][10]={};
  int rows;
  int cols;
  int i,j,search;
  char A,B,C={'A','B','C'};
  printf("MENU\n");
  printf("A. INSERT\n\nB. PRINT\n\nC. SEARCH\n\nD. EXIT\n\n");}
  if(A==A);
  {scanf("Enter the number of rows:," &rows")";
  scanf("Enter the number of columns:," &cols")";
  for(i=0; i<rows; i++){
  for(j=0; j<cols; j++){
  scanf("Enter a number," &array[rows][cols]")";
  }}
  }
  else if(B==B);
  { for(i=0; i<rows; i++){
  for(j=0; j<cols; j++)
  printf("%d\t,"array[rows][cols]);
  }}
  else if(C==C);
  {scanf("Enter the number you want to find:," &search")";
  for(i=0; i<rows; i++){
  for(j=0; j<cols; j++){
  if(search==array[rows][cols]);{
  printf("The element %d is on
  (%d,%d),"search, rows, cols);}
  else
  {printf("The element is not found.");
  }}}
  }
  else{};
  return 0;
  }
