A exam. 20 points problem:
int** createMatrix(int rows, int cols) {
int** matrix = new int*[rows];
for (int i = 0; i < rows; i++) {
matrix[i] = new int[cols];
}
for (int i = 0; i < rows; i++) {
for (int j = 0; j < cols; j++) {
matrix[i][j] = i + j;
}
}
return matrix;

A exam. 10-point problem
#include <iostream>
using namespace std;
int lcm(int num1, int num2) {
int a = num1;
int b = num2;
while (b>0) {
a = a%b;
int temp = b;
b = a;
a = temp;
}
return num1*num2/a;
}
int main() {
cout << lcm(48,18);
return 0;
}
