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 dimensionprint array[i][j]} }

How do you exit in nested loop in java?
You may exit a nested loop in Java using a break with a label for the outer loop.
In C which loop is embedded within another loop?
The nested loop.
When loops are nested does one loop have to end before the other begins?
If one loop ends before the next begins then they are not nested at all -- they are completely independent. To be nested, one loop must contain the other loop in its entirety. That is, the inner, nested loop must start and end within the outer, containing loop. Nested loop example (in C++): for( int x = 0; x < 10; ++x ) // outer loop { for( int y = 0; y < 10; ++y ) // inner loop (nested loop) { printf( "%d x %d = %d\r\n", x, y, x*y ); } // end of inner loop } // end of outer loop
Why you use inner loop and outer loop?
Sometimes you have to use nested loops, in this case one of them is the outer, the other is the inner.
How do you get your nested loop to decrement and not increment?
Easy. Change any + to -, any += to -=, any ++ to --

What is meant by nested looping in programming?
A nested loop is when you have a loop in a loop. So this code: for(int i = 0; i < 3; i++) { for(int j = 0; j < 3; j++) { cout << "i: " << i << "j: " << j << endl; } } will output 0,0 0,1 0,2 1,0 1,1 1,2 2,0 2,1 2,2

The nested loop.
What is a nested loop in java?
A nested loop is a (inner) loop that appears in the loop body of another (outer) loop. The inner or outer loop can be any type: while, do while, or for. For example, the inner loop can be a while loop while an outer loop can be a for loop.
How do you use nested for loop on the image in matlab?
Please ask clearly what you want to do with the image and explain why a nested for-loop is necessary.
What is the definition of 'nested' in C programming?
In C a structure within a structure is called nested. For example, you can embed a while loop in another while loop or for loop in a for loop or an if statement in another if statement.
What is the time complexity of a nested while loop?
The time complexity of a nested while loop is O(n2), where n represents the size of the input data. This means that the execution time of the nested while loop increases quadratically as the input size grows.
Which loop is used when two things are done at the same time?
A loop inside a loop, which is known as a nested loop.

What is the time complexity of a nested for loop in terms of Big O notation?
The time complexity of a nested for loop is O(n2), where n represents the size of the input data.
