I wrote I little program to read in numbers from a user and print the
numbers by Rows, Columns. I need to add together the Columns for an output.
I'm stuck on this one!
Ex: 23        45        65        23
       12        3            6        2

        35        48        71        25      (total)

This is what I should get but I can't figure out how to add the columns
together. I get the rows, and columns. I'm looking for suggestion on this
one.

Thanks

#include <stdio.h>

void get_rc(int row, int col);

main(void)
{
 int row, col;
 clrscr();
 gotoxy(25,8);
 printf("Please Enter Number of Rows : ");  /*Get number of rows from user
*/
 scanf("%d",&row);
 gotoxy(25,10);
 printf("Please Enter Number of Columns: ");
 scanf("%d", &col);   /* Get number of columns from user */
 get_rc(row, col);
 return;

void get_rc(int row, int col)
{
 double table[10] [10];
 double add;
 int r,c;
 clrscr();
 gotoxy(28,4);
 printf("Please enter numbers\n\n"); /* Enter numbers into table */
 for (r=0; r<row; r++)
 {
  for (c=0; c<col; c++)
  {
   printf("Enter element [%d] [%d]:", r, c);
   scanf("%lf", &table[r] [c]);
   }
    printf("\n");
  }
    clrscr();
    for (r=0; r<row; r++)   /* print table rows-columns to screen */
    {
    for (c=0; c<col; c++)
     {
    printf("%lf\t", table [r][c]);
   }
    printf("\n");

    }
    printf("\n");   /* PROBLEM CODE, CAN"T ADD TOGETHER */
    for (c=0; c<col; c++) /* add columns together for output total*/

    printf("%lf", add);
    }
    getch();
  return;

two dimensional arrays have to parts to the array
Array[a][b]
two for loops
for(a=0;a< YOUR MAX FOR A; a++){
for (b=0; b<YOUR MAX FOR B; b++)
{ sum=Array[a][b];}
That should do it.

Array[a][b]
two for loops
for(a=0;a< YOUR MAX FOR A; a++){
sum=0;
for (b=0; b<YOUR MAX FOR B; b++)
{ sum+=Array[a][b];}
print sum
assuming a represents columns and b represents rows, or else interchange the
for loop.

hope this helps
