nested loops any one explain me in easy way plz

Answer 1

thankx boris ❤️

Answer 2

Simply, if you put a loop in another loop, you'll have a nested loop.

Example 1:
for (int i = 0; i < 3; i++) {
for (int j = 0; j < 5; j++) {
cout << j;
}
cout << endl;
}

Output:
01234
01234
01234

As you can see, on each iteration of the outer loop you execute the inner loop.

Example 2:
for (int i = 0; i < 2; i++) {
cout << "i = " << i << endl;
for (int j = 0; j < 4; j++) {
cout << "j = " << j << endl;
cout << "k = ";
for (int k = 0; k < 6; k++) {
cout << k;
}
cout << endl;
}
cout << endl;
}

Here you'll get 2(i) x 4(j) of 012345(k).
You can practice it in the playground.
