besides the fact that you are adding an uninitialized (so random memory dump) value to the sum, perhaps you can add a comment to how int_avg is calculated...


int_avg = int_age3 + int_age;

just as a side note, why not use an array?

One wouldn't use an array in this case because we don't care to store any individual's age, and only care about the total.

Though with that in mind, asking for a person's name is quite redundant.

I understand the basis of my code and im fine with it but i just need help with the average. I get the average by adding int_age2 to int_age 3 everytime the loop occurs. Than this total age is added with the age enter outside the loop (int_age) which is finally all posted by a variable called int_avg. Also I dont think i have an uninitialized value. All of my values are initialized. I did a few variable traces but everything still looks like it should work. Here is a list of the values of each variable (which affect the average):

int_age - is defined by the user
int_age2 - is defined at the start as 0 as to ensure that that is where the counting starts.
And the rest are just like int_age2
(
int int_age;
int int_age2;
int int_age3;
int int_avg=0;
int int_num=0; 
)

Alright I'm sorry I gave you really bad code here is the update!
#include 
#include 

int main()
{
      char str_name [30];
      char str_name2 [30];
      int int_age;
      int int_age2=0;
      int int_age3=0;
      int int_avg=0;
      int int_num=0;
      printf("Please enter the name of person #1: ");
      scanf(" %s", str_name);
      printf("Please enter the age of person #1: ");
      scanf(" %d", int_age);
      for(int_num = 2; int_num
