Draw a flowchart with correct symbol representation to the below code #include using namespace std; int main() { int firstterm,secondterm,thirdterm; int commondiffrence,term; cout << "enter the first term: "; cin >> firstterm; cout << "enter the second term:"; cin >> secondterm; cout << "enter the third term: "; cin >> thirdterm; commondiffrence = secondterm - firstterm; cout << "common diffrence : "<< commondiffrence << endl; cout << "SUM OF THE FIRST n TERMS is: " << 300/2*(2*(firstterm) + (300 - 1)*commondiffrence) << endl; cout << "SUM OF THE FIRST 50 TERMS ARE :"; for (int i=0; i<50; i++) { term = firstterm + i * commondiffrence; cout << term << " "; } return 0; }

4. Correct and detailed answer will be Upvoted else downvoted. Thank you!
