Question

What will be the output of the following code

#include <iostream>

using namespace std;

int main () {

int n[3][4]={{12,-13,10,4},{9,2,34,2},{12,13,5,6}};

int i,j,v;

v = n[0][0];

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

    for (j=0; j<4;j++) {

        if (n[i][j]>=v) v=n[i][j];

        }

cout << v <<endl; return 0;

}

1) Error in the code.      2) 34          3) -13            4) 12

Answer 1

4) 12

it's a linear search algorithm to search for the largest number

Answer 2

second option is correct because initially v will have value equal to 12 but when control will come in 2nd row then value of v will be 34 and as we all know that a variable can hold only one value at a time and no other value in this 2D array is greater than 34 so output i.e value of v will be 34

Answer 3

Answer is : 34.

Answer 4

1) Error in this code

iostream.h

Answer 5

The answer is :2

Answer 6

12 is the output

Answer 7

value of v will be 34. as when i counts the value turns 12 but in 2d array the  no gets multiplied by it i.c 3 therefore 34.
