C :: Average And Total Of Six Integers

"Write a program that prompts the user for an integer number from the keyboard, and store it in a variable num. After each number is typed in, add num to a total.

Do this six times, each time adding num to a total. (Be sure to reuse the same variable named num for each of the six numbers entered.) When all six numbers have been entered from the keyboard, calculate an average. Display the total and average calculated. "

Here is what I have so far:

Code:
#include<stdio.h>
int main() {
int num, total1, total2, total3, total4, total5, total6, avg;

printf("Enter first number:");
scanf("%2d",&num);
