What are nested loops in C programming?

Nested loops in C are loops within loops, allowing for multi-dimensional iteration.

Can you give me an example of nested loops in C?

Sure! Here's a simple example:

#include <stdio.h>

int main() {
    for(int i = 0; i < 3; i++) {
        for(int j = 0; j < 2; j++) {
            printf("i: %d, j: %d\n", i, j);
        }
    }
    return 0;
}

What is the output of that code?

The output will be:

i: 0, j: 0
 i: 0, j: 1
 i: 1, j: 0
 i: 1, j: 1
 i: 2, j: 0
 i: 2, j: 1

Are there any performance considerations with nested loops?

Yes, nested loops can lead to increased time complexity, especially with large datasets. It's important to optimize them.
