        {

            sum+=a[i][j];

Hi ash_rock,

Check out the code below -

#include <iostream.h>


int main()

{

int x[3][3]={{12,44,55},{34,7,10},{3,30,20}};

for(int i=0;i<3;i++)

{

int sum=0;

for(int j=0;j<3;j++)

    sum+=x[i][j];

cout<<i<<" row sum: "<<sum<<endl;

}

return 0;

Hi bharathraj, Your both

Hi bharathraj,

Your both codes are almost correct. You just NEED to make sum variable equal to zero BEFORE the second loop begins.
