Question

Given the following 2D array double nums[MAXROW][MAXCOL] = {{ 7, 12, 8, 23, 43, 16, 9, 15}, {21, 7, 14, 48, 13, 6, 43, 29), {11, 2, 17, 91, 36, 14, 65, 43), {18, 5, 47, 38,52, 1, 18, 26}}; int numRows = 4; int numCols = 8; Write a function called totalRow that has the array, the number of rows, and the number of columns passed in. It will then print the total of the row that has 11, 2, 17, 91, 36, 14, 65, and 43.in it. It does not return anything and it always prints the total of the elements in that row. [Note: you may not need all of the arguments being passed in, but pass them in anyway)

Answer 1

HERE THE PROGRAM IS DONE WITH C++ LANGUAGE

IN THIS PROGRAM ALL THE ARGUMENTS ARE PASSED IN THE FUNCTION.

PROGRAM

#include<iostream>
/* here we define macro of MAXROW and MAXCOL as 20 */
# define MAXROW 20
# define MAXCOL 20
using namespace std;
/* totalRow function has three arguments */
totalRow(double nums[MAXROW][MAXCOL],int numRows,int numCols)
{
   int i,j;
   double s=0.0;
   /* scan the 2d array */
   for(i=0;i<numRows;i++)
   {
   for(j=0;j<numCols;j++)
   {
       /* check if row index is 2 then the values will be added */  
   if(i==2)
   {
   /* added values */
       s=s+   nums[i][j];
       }
    }
   }
   /* print the total */
   cout<<"Total is : " <<s;
}
main()
{
   /* define and initialize the 2d array */
   double nums[MAXROW][MAXCOL]={{7,12,8,23,43,16,9,15},
   {21,7,14,48,13,6,43,29},
   {11,2,17,91,36,14,65,43},
   {18,5,47,38,52,1,18,26}};
     
/* total row and colum numbers are given */
   int numRows=4;
int numCols=8;
/* call function totalRow with array, number of rows and number of columns */
totalRow(nums,numRows,numCols);
}

SCREEN SHOT

main() /* define and initialize the 2d array */ double nums[MAXROW][MAXCOL]={{7,12,8,23,43,16,9,15}, {21, 7, 14,48,13,6,43,29}, {11,2,17,91,36,14,65,43}, (18,5,47,38,52,1,18,26}}; /* total row and colum numbers are given */ int numRows=4; int numCols=8; /* call function total Row with array, number of rows and number of columns */ totalRow (nums, numRows, numCols);
