Well, you dumped some code (unreadable because you didn't use code tags) and failed to state what your problem was.

What help do you need?

PLEASE ALWAYS USE CODE TAGS (the <> formatting button) when posting code.
It makes it easier to read your code and also easier to respond to your post.

Hint: You can edit your post, highlight your code and press the <> formatting button.

Line 39: This } terminates main. All the remaining statements are outside of a function which is an error. Did you mean { ?

Note. Check L93 produces the correct result.

Also note that there's no checks for valid/invalid input.

I see you haven't fixed line 39 as I pointed out in my forum reply.

Line 9,53,61: Should be 'S', not "S". Single quote, not double.

Line 20 should be: right << setw(21) Should be <<, not <

Line 73,74: Missing a close quote
cout << "Total payment for Social media marketing (M) is :"
cout << "Total payment for Email marketing (t) is :"


Line 43: You're using the return value from calPayment, but calPayment doesn't return a value if you fall through the if statements.

Lines 54,56,58: round() returns a double. discount is an int. If you want to assign a double to an int, you must cast it.

Line 75: You need to adjust your parens:

int highest = total_s > total_m ? (total_s > total_e ? total_s : total_e) : (total_m > total_e ? total_m : total_e);
