Data Collection

Data Collection program

A survey was carried out among fifteen inhabitants of a region. These data were collected from each inhabitant in order: age, sex (M or M), salary and number of children. Make a subroutine that reads this data by storing it in arrays. Create subroutines that receive these vectors as parameters and return the average salary among the inhabitants, the youngest and oldest age of the group and the number of women with three children who receive up to $500.00. Use a subroutine for each calculation.

Execute

Clone main branch from c-cpp-projects.

Access this folder on terminal:

  cd c-cpp-projects/c_exercises/data_collection
