Vector M dan kata elementlarini ko`paytmalarini logarifmi hisoblansin.

#include

#include
#include

using namespace std;

int main() {
vector M = {1.0, 2.0, 3.0, 4.0, 5.0};
vector result;

for (int i = 0; i < M.size(); i++) {

double value = log10(M[i]);
result.push_back(value);
}

cout << "M: ";

for (double element : M) {
cout << element << " ";
}

cout << endl << "Result: ";

for (double element : result) {
cout << element << " ";
}

cout << endl;

return 0;
}

Bu kodda, vector tipida M yaratilgan va 1.0, 2.0, 3.0, 4.0, 5.0 qiymatlarini o'z ichiga olgan. M ning har bir elementining logarifmini hisoblash uchun for loop dan foydalanilgan va natijalar vector tipidagi result ning ohiriga qo'shilgan. Natijalar ekranga chiqarilgan.

a Vektorning juft qiymatli elementlarini b Vektorga, toq qiymatli elementlarini с Vektorga joylashtiring.

#include

#include

using namespace std;

int main() {
vector a = {1, 2, 3, 4, 5};
vector b;
vector c;

for (int i = 0; i < a.size(); i++) {

if (a[i] % 2 == 0) {
b.push_back(a[i]);
} else {
c.push_back(a[i]);
}
}

cout << "a: ";

for (int element : a) {
cout << element << " ";
}

cout << endl << "b: ";

for (int element : b) {
cout << element << " ";
}

cout << endl << "c: ";

for (int element : c) {
cout << element << " ";
}

cout << endl;

return 0;
}

Vektor max elementi bilan k chi elementi o‘rnini almashtiring.

#include

#include
#include

using namespace std;

int main() {

vector a = {10, 20, 30, 40, 50};
int k = 2;

auto it = max_element(a.begin(), a.end());

int max_element_index = distance(a.begin(), it);

if (max_element_index >= k) {

swap(a[max_element_index], a[k]);
}

cout << "a: ";

for (int element : a) {
cout << element << " ";
}

cout << endl;

return 0;

}

Bu kodda, vector tipida a yaratilgan va 10, 20, 30, 40, 50 qiymatlarini o'z ichiga olgan. k esa almashtirish kerak bo'lgan elementning indexini ifodalaydi. max_element funktsiyasi yordamida a ning eng katta elementining indexi aniqlanadi va distance funksiyasi orqali o'rnini topadi. Agar max_element_index k dan katta yoki teng bo'lsa, max_element_index elementi k elementi bilan almashtiriladi. Natijalar ekranga chiqarilgan.
