Question

Read the file and make a vector with the total for each Gender/Alchohol frequency. C++

Ask the user for an age range (min and max) Search the file to collect the information the user asked for Display the data as a bar chart Details You want to read the file and make a vector with the total for each Gender/Alcohol frequency. The vector will have 10 spaces, they are numbered 0-9. We need to encode the gender and frequency into these spaces. The gender can be either M or F. The frequency can be 1 (very low) to 5 (very high). To fit these in the numbers 0-9, we can store M values in even spaces and F values in odd spaces. If M then store in position: frequency*2-2 If F then store in position: frequency*2-1 Remember to take into account that the user only cares about certain ages. In each position of the vector, count how many people met the requirement. If 7 males said they drank with frequency 1, then the position 0 in the vector should store 7. (1 *2-2=0) To make the data easy to visualize, draw it as a bar chart. Draw an X for a count of 10 and show the remainder as an integer. Here are some function prototypes that may help you. You are not required to use them, they are only a suggestion.//Searchs the file given and fill in a vector with the number//of people who drink at each level 1-5, for both males and females//Only count people with min_age <= age <= max_age void analyze(string filename, vector<int> & results, int min_age, int max_age);//Prints out the vector as a bar chart void print_chart(vector<int> & results);//Print a single row X for a 10, int 1-9 for remainder//Example: Prints 27 as XX7 and 31 as XXX1 void print_bar(int num);
