Which of the following statements is true about nested loops?a)Nested ...
Nested loops are loops that are placed inside other loops. They allow us to repeat a set of instructions multiple times within another set of instructions. In programming, both while loops and for loops can be nested.
Explanation:
Nested loops are commonly used when we need to perform repetitive tasks that require multiple levels of iteration. They allow us to iterate over a set of values for one variable while iterating over another set of values for another variable.
Benefits of Nested Loops:
Nested loops provide several benefits in programming, including:
1. Complex Iteration: Nested loops allow us to iterate over complex data structures, such as multi-dimensional arrays or matrices. For example, we can use a nested loop to iterate over the rows and columns of a 2D array.
2. Pattern Generation: Nested loops can be used to generate patterns or sequences of numbers. By controlling the number of iterations and the values of the loop variables, we can create various patterns, such as triangles or squares.
3. Search and Filtering: Nested loops can be used to search for specific elements or perform filtering operations. For example, we can use nested loops to search for a particular value in a 2D array or to filter a list based on certain conditions.
Example:
Here is an example of a nested for loop in C programming language:
```
for (int i = 1; i <= 3;="" i++)="">
for (int j = 1; j <= 3;="" j++)="">
printf("%d ", i * j);
}
printf("\n");
}
```
This nested loop will iterate over the values of `i` from 1 to 3 and the values of `j` from 1 to 3. It will print the product of `i` and `j` on each iteration, resulting in the following output:
```
1 2 3
2 4 6
3 6 9
```
As we can see, the nested loop allows us to perform a repetitive task (printing the product of `i` and `j`) multiple times within the outer loop.
Therefore, the correct statement is option 'C': Both while loops and for loops can be nested.

Which of the following statements is true about nested loops?a)Nested ...
Both while loops and for loops can be nested inside each other. This means you can have a loop within another loop, allowing for more complex control flow and iterative operations.
