Yes, sometimes it is possible. It depends on what the nested loop actually does of course, but there are cases where a single loop can achieve the same end.
For instance, the following nested loop prints the product of each pair of values in the range 1 to 10:
for( int x=1; x<=10; ++x )
for( int y=1; y<=10; ++y )
printf( "%d * %d = %d\r\n", x, y, x*y );
This could be written as a single loop:
for( int z=0; z<100; ++z )
{
int x = z/10+1;
int y = z%10+1;
printf( "%d * %d = %d\r\n", x, y, x*y );
}
Note that the nested loop is easier to read and maintain and is also much more efficient than the merged loop.

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.
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
In C which loop is embedded within another loop?
The nested 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.
What is nesting loop?
Nested loop, you mean; one loop in the other loop, eg: for (i=0; i<10; ++i) { for (j=0; j<i; ++j) { printf ("i=%d, j=%d\n", i, j); } }

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.
Why you use inner loop and outer loop?

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 nesting loop?

Why are nested for loops used in java?
Nested loops can be used in any language. They are used for situations where you may need two levels of repetition. So you could be printing a list of teams, which is one loop, and for each team the name of its players, and that would be the inner loop. If you know there is a set amount of players and teams, a For loop would be appropriate. You could have a loop that displays the 7 days of the week and for each day, the on the hour times, so that would require two For loops with the hours one nested in the days one. There are all sorts of situations where you would use them.

How do you get your nested loop to decrement and not increment?
Easy. Change any + to -, any += to -=, any ++ to --
