Adding two matrix using two dimension array

Posted by MindBreaker at 1:54 AM Read our previous post

Suppose A and B are n-elements vector array in memory and X an Y

are scalars. Write a program to find.

a) XA + YB

b) A . B

Test the program using A= (16, -6,7), B=(4,2,-3), X= 2, Y= -5

Source Code;

#include <iostream>

using namespace std;

int main()

{

       int ary1[2][3]={

              {2,3,4},

              {5,6,7},

      

       };

       int ary2[2][3]={

              {8,0,5},

              {5,1,2},

      

       };;

       int ary3[2][3]={

              {6,3,4},

              {2,7,5},

      

       };;

       int x=2,y=5,count1,count2;

       for(count1=0;count1<2;count1++)

       {

       for(count2=0;count2<3;count2++)

       {

       ary1[count1][count2]*x;

      

       ary2[count1][count2]*y;

       }

       }

       for(count2=0;count2<2;count2++)

       {

       for(count2=0;count2<3;count2++)

       {

       ary1[count1][count2]*x+ary2[count1][count2]*y;

       }

       }

       for(count1=0;count1<2;count1++)

       {

       for(count2=0;count2<3;count2++)

       {

       ary3[count1][count2]=ary1[count1][count2]*x+ary2[count1][count2]*y;

       }

       }

       for(count1=0;count1<2;count1++)

       {

       for(count2=0;count2<3;count2++)

       {

              cout<<ary3[count1][count2]<<" , ";

       }

       cout<<endl;

       }

return 0;

}

Output:
