Answer:
b-Nested Loops
Explanation:
To create a 1-D array we use single loop.For example:-
int a[10];
for(int i=0;i<10;i++)
{
cin>>a[i];
}
Taking input of a 1-D array.
For creating a 2-D array we use nested loops.
int a[row][column];
for(int i=0;i<row;i++)
{
for(int j=0;j<column;j++)
{
cin>>a[i][j];
}
}
Hence the answer for this question is nested loops.
