The program is an illustration of loops.
Loops are used to perform repetitive and iterative operations.
The program in C++ where comments are used to explain each line s as follows:
#include <iostream>
#include <vector>
using namespace std;
//This defines the vector_sort function
void vector_sort(vector<int> &vec) {
//This declares temp as integer
int temp;
//This iterates through the vector elements
for (int i = 0; i < vec.size(); ++i) {
//This iterates through every other vector elements
for (int j = 0; j < vec.size() - 1; ++j) {
//The following if condition sorts the vector elements
if (vec[j] > vec[j + 1]) {
temp = vec[j];
vec[j] = vec[j + 1];
vec[j + 1] = temp;
}
}
}
}
//The main method begins here
int main() {
//This declares the vector size and the inputs as integers
int size, n;
//This declares the vector as integer
vector<int> v;
//This gets input for the vector size
cin >> size;
//The following iteration gets input for the vector
for (int i = 0; i < size; ++i) {
cin >> n;
v.push_back(n);
}
//This calls the vector_sort method
vector_sort(v);
//The following iteration prints the sorted vector
for (int i = 0; i < size; ++i) {
cout << v[i] << " ";
}
return 0;
}
