Answer to Question #189737 in Visual Basic for maria

Question

Code a program to get the number of students and the group size from the user. Calculate and display the number of groups that must be used to divide the students in the given group size. The last group would possibly not be filled. Display also the number of students in the last group.  

 

Functions to code and use: 

• CalcNumberGroups. This function must get the number of students and the group size via parameters. It must calculate and return the number of groups (integer) that would be used. 
• CalcLastGroupSize.  This function must get the number of students and the group size via parameters. It must calculate and return number of students (integer) in the last group.

Example:

If there are 23 students and they must be divided into groups of 6, then there will be 4 groups. The last group will have 5 members.
