5.18 Ch 5 Warm up: People's weights (Vectors) (C++) (1) Prompt the user to enter five numbers, being five people's weights. Store the numbers in a vector of doubles. Output the vector's numbers on one line, each number followed by one space. (2 pts) Ex: Enter weight 1: 236.0 Enter weight 2: 89.5 Enter weight 3: 142.0 Enter weight 4: 166.3 Enter weight 5: 93.0 You entered: 236 89.5 142 166.3 93 (2) Also output the total weight, by summing the vector's elements. (1 pt) (3) Also output the average of the vector's elements. (1 pt) (4) Also output the max vector element. (2 pts) Ex: Enter weight 1: 236.0 Enter weight 2: 89.5 Enter weight 3: 142.0 Enter weight 4: 166.3 Enter weight 5: 93.0 You entered: 236 89.5 142 166.3 93 Total weight: 726.8 Average weight: 145.36 Max weight: 236
