How do you use nested loop?

In: Computer Programming [Edit categories]

Answer:

A nested loop is just one loop within another. The most common use of this is to read from or write into a multi-dimensional array.

Example (in C-style pseudocode):

int[][] array = some collection of data

for( int i = 0; i < array.length; ++i ) { // loop through first dimension

for( int j = 0; j < array[0].length; ++j ) { // loop through second dimension

print array[i][j]

}

}
