What is the index of a loop?

An index loop repeats for a number of times that is determined by a numeric value. An index loop is also known as a FOR loop.

What is the rule of nested loop?

In a nested loop, a break statement only stops the loop it is placed in. Therefore, if a break is placed in the inner loop, the outer loop still continues. However, if the break is placed in the outer loop, all of the looping stops.

What is a nested loop and how does it work?

A nested loop is a loop within a loop, an inner loop within the body of an outer one. How this works is that the first pass of the outer loop triggers the inner loop, which executes to completion. Then the second pass of the outer loop triggers the inner loop again. This repeats until the outer loop finishes.

How do you find the loop index?

You can access the index even without using enumerate() .

  1. Using a for loop, iterate through the length of my_list . Loop variable index starts from 0 in this case.
  2. In each iteration, get the value of the list at the current index using the statement value = my_list[index] .
  3. Print the value and index .

What is loop index in C?

The index is the variable which you use to to keep track of the iterations of the loop. Generally index variables are integers, but they don’t have to be. In this code example – the variable ind is the index variable in the for loop. int my_strcmp(char *first, char *second) {

What is nested loop in C with example?

The nesting level can be defined at n times. You can define any type of loop inside another loop; for example, you can define ‘while’ loop inside a ‘for’ loop. // inner loop statements….while’ loop.

  • do.
  • {
  • do.
  • {
  • // inner loop statements.
  • } while(condition);
  • // outer loop statements.
  • }while(condition);

Why do we use nested loops?

Nested loops are extraordinarily useful when you have two different arrays that need to be looped through the same function, looping different arrays into properties of various objects, when you need a ā€œ2Dā€ array (x and y-axis), and the list goes on.

What is nested loop with example in C?

Nesting of loops is the feature in C that allows the looping of statements inside another loop. Let’s observe an example of nesting loops in C. Any number of loops can be defined inside another loop, i.e., there is no restriction for defining any number of loops. The nesting level can be defined at n times.
