I have 2 programs that I need help with in C

Program 1 = (converting strings to integers for calculations), write a program that input six strings that represent integers, converts the strings to integers and calculates the sum and average of the six values.

Program 2= (Strings starting with "Th"), write a program that reads a series of strings and prints only those beginning with the letters "Th".

These are the only programs I need help with right now, please help me with the answers, They are required in C langauge and plese make sure they work on the online complier of microsoft visual studio.
