Question

Define a class to accept values into a 4 × 4 array and find and display the sum of each row.

Example:

A[][]={1,2,3,4),{5,6,7,8},{1,3,5,7},{2,5,3,1}}

Output:

sum of row 1=10 (1+2+3+4)

sum of row 2=26 (5+6+7+8)

sum of row 3=16 (1+3+5+7)

sum of row 4=11 (2+5+3+1)

Answer 1

class sumrow
{
   int x[][]=new int[4][4];
   sumrow(int z[][])
   {
     x=z;
   }
   void calculate()
   {
     int r,c, s=0;
     for(r=0;r<4;r++)
     {
       for(c=0;c<4;c++)
       {
          s=s+x[r][c];
       }
       System.out.println("sum of row="+r+"="+s);
       s=0;
     }
   }
}
