What is the output of the following present is estimate #include using namespace std; int main () {const int HEIGHT= 3, WIDTH = 3; int sum; int myArray [HEIGHT] [WIDTH] = {{1, 1, 1}, {2, 2, 2}, {3, 3, 3}}; for (int i = 0; i

Solution

OutPut:

for(int i=0;i<HEIGHT;i++){ // This loop go through Row wise

sum=0;

for(int j=0; j<WIDTH;j++)// This loop go through column wise

{

sum= sum +myArray[i][j];// In first loop i=0; and j changes value by second loop so it will j=0,1,2

myArray[i=0][j=0]=1,myArray[i=0][j=1]=1,myArray[i=0][j=0]=1,Ans Sum become sum= 3, similary for i=1,and j=0,1,2, sum become 6 and i=2 and j=0,1,2 sum become 9

}

}

so output uper nested loop:

3 6 9

for(int j=0; j<WIDTH;j ++){

sum=0;

for(int i=0;i<HEIGHT;i++){

sum= sum+ myArray[i][j]; // in outer loop time of loop j=0; inner loop takes values i=0,1,2 and myArray takes value myArray[i=0][j=0]=1, myArray[i=1][j=0]=2, myArray[i=2[[j=0]=3 and sum become 6

and again for outer loop take j=1, inner loop i=0,1,2 and myArray[0][1]=1,myArray[1][1]=2,myArray[2][1]=3, and sum=6,

and similary for j=2, i =0,1,2 and myArray[0][2]=1;myArray[1][2]=2;myArray[2][2]=3; and sum= 6

}

}

output by lower nested loop:

6 6 6

OverAll Output:

3 6 9

6 6 6
