I am confused in second part and c++ declaration help!!

Archie wants a program that calculates and displays a team's final score in a football game, given the numbers of the team's field goals, touchdowns, one-point conversions, two-point conversions, and safeties. First, create an IPO chart for this problem, and then desk-check the algorithm twice. For the first desk-check, use 3, 2, 2, 0, and 1 as the numbers of field goals, touchdowns, one-point conversions, two-point conversions, and safeties. For the second desk-check, use your own set of data. After desk- checking the algorithm, list the input, processing, and output items in a chart similar.to the one shown in Figure 3-25, and then enter the appropriate C++ declaration statements IPO Chart Input Processing Output Field goals a- field goal3 Display final score Touchdowns - touchdown 6 One-point conversion Two-point conversion Safeties c- one-point conversion *1 d- two-point conversion *2 safeties *2 Final score-at tctdte Desk check 1 input (3,2.2,0,1) Numbers Input Processing Output b 2*6-12 c 2*1- 2 d-0*2 0 10 12 13 Final score- 9+122+0+2-28
