text: The cube sum of first n natural numbers is the program to add cubes of all natural numbers up to n. It is sum of series 1^3 + 2^3 + …. + n^3 that is sum of cube of n natural numbers.
  Input:6 Output:441
  1^3 + 2^3 + 3^3 + 4^3 + 5^3 + 63 = 441
  Using For loop to increase the no. and cubing it and taking sum of them.
  #include <iostream> using namespace std; int main() { int n = 6; int sum = 0; for (int i = 1; i <= n; i++) { sum += i * i * i; } printf(“%d”, sum); return 0; }
