return largerst line from 2D array

December 7, 2021

I need help with a function that finds the line with the largest number of numbers in a two-dimensional array and prints index this row. I don’t know how to start for help thank you.

main.c

int array[2][2]=  { {1,0}, {0,3} };
printf("%d\n", largest_line(2, array));

int largest_line(const int size, int array[][size]){

for(int col= 0; col < size; col++){
    for(int row = 0; row <size; row++){
     // and on this place I stop 
    }
}
}

>Solution :

Something like this should work for you:

int largest_line(const int size, int array[][size]){

    int largest_number = 0;
    int largest_row = 0;

    for(int col= 0; col < size; col++){
        for(int row = 0; row <size; row++){
            if(largest_number > array[col][row]) {
                largest_number = array[col][row]);
                largest_row = row;
            }
        }
    }
    return largest_row;
}
