Given the following C++ program below. Complete the program by wrting the functions InputRideData, AvgDuration, CountGender, AvgAgeOfGender, and SearchForBikeID. What each function should contain is in the comment above the name of the function as shown. The two filnames are data1.txt and data2.txt. The files contain in a single row; the bikeid, duration, gender, and birthyear. Data1.txt contains the following:

3808 311 1 1984 1756 309 1 1991 253 524 1 1973 253 423 1 1973 881 477 1 1990 519 535 1 1972 1756 321 1 1993

Data2.txt contains the following data:

609 1045 1 1993 1207 1035 1 1993 4369 1166 1 1988 2703 1348 2 1992 3828 1101 1 1987 4377 199 1 1984 3115 439 1 1984

After filling out the functions, run the program and produce your output.
