Explanation / Answer

A.So for the following given array int scores[3][3] = { {1, 2, 3} };

if we execute the code we will get an output as 0, because we are declaring a 2-D Array but the fixed values declared are not enough, so if any of the value is printed/requested which is not defined or assigned, so the Output is undefined or is a Garbage Value 0.

You can run the given code and try yourself

#include <stdio.h>

int main(void)
{
int scores[3][3] = { {1, 2, 3} };
printf("%d",scores[2][2]);
   return 0;
}

B.An array is a group of related _____ that have the same data type.

So Array is a group of related elements that have the same data type.

It could be Variables also in some cases but of the same type.

C.One dimentional Array can be visualized as a coloumn of related elements, as an array can represent only one kind of data.If we visualize a 2-D Array of two different kind of data, it would voilate the properties of an Array.

D.Here again the requested value is not defined in the fixed array.

So the requested value, which is not in the Array will show a Value 0 or a Garbage Value.

You can run the given code and try yourself

#include <stdio.h>

int main(void)
{
int scores[5][5] = {5};
printf("%d",scores[2][3]);
   return 0;
}
