Nesting loops is when one or more loops are nested inside another loop. In C language, nested loops can be used to achieve this structure. Here is a simple example code demonstrating how to write nested loop code:

#include <stdio.h>

int main() {
    int i, j;
    
    // 外层循环
    for(i = 1; i <= 5; i++) {
        printf("外层循环执行第%d次\n", i);
        
        // 内层循环
        for(j = 1; j <= i; j++) {
            printf("内层循环执行第%d次\n", j);
        }
    }
    
    return 0;
}

In this example, the outer loop runs 5 times, and the inner loop executes a number of times equal to the current value of the outer loop. You can adjust the starting value, end value and increment of the loop, as well as the logic of the inner loop, to design your own nested loop structure.
