help me understand the loops
#include<stdio.h> void main() { int i, j, a, n, number[30]; printf("Enter the value of N \n"); scanf("%d", &n); printf("Enter the numbers \n"); for (i = 0; i < n; ++i) scanf("%d", &number[i]); for (i = 0; i < n; ++i) { for (j = i + 1; j < n; ++j) { if (number[i] > number[j]) { a = number[i]; number[i] = number[j]; number[j] = a; } } } printf("The numbers arranged in ascending order are given below \n"); for (i = 0; i < n; ++i) printf("%d\n", number[i]); }
