C Assignment Help
I'm in college and I have to do an assignment on Abundant Numbers (Programmed in C).

Assignment Details are pretty straight forward. Ask for a number determine if it is abundant.
-Use "boolean" function to test a number for abundance.
-use a function to control output and another for input.
-An Abundant Number is a positive integer whose integer factors less than itself sum to a value greater than it.

This is the Code I have so far:
Code:

```#include <stdio.h> #include <math.h> int Input(int N) {         printf("Enter the Nth Abundant Number you wish to see: ");         scanf("%d", &N);         return(N); } int Calc(int N) {         int Sum, I, I2;           Sum = 0;         I2 = sqrt(N);         for (I = 1; I >= I2; I++)                 if ((N % I) = 0) Sum += I + (N / I);         return(Sum); } int Check(int N, int Sum, int Abundancy) {         if (Sum > N)                 Abundancy = 1;         else                 Abundancy = 0;         return(Abundancy); } int Output(int Number, int Abundancy) {         if (Abundancy == 1)                 printf("%d %s", Number, "is Abundant");         else                 printf("%d %s", Number, "is not Abundant"); } int main() {         /* Variables */         int N, Sum;         int Abundancy;                 /* Start Loop */         while (N != 0)         {                 /* Input */                 N = Input(N);                 for(int I = N; I = (N - 10)or I <= 0; I--)                 {                         /* Calculate */                         Sum = Calc(N);                                        /* Determine Abundancy */                         Abundancy = Check(N, Sum, Abundancy);                                                        /* Output */                         Output(N, Abundancy);                 }         }        }```
Could someone help me figure out why it declares everything as not an abundant number?
my test is 12. 1 + 2 + 3+ 4+ 6 = 16, 16 > 12, so it is abundant.

>> for (I = 1; I >= I2; I++)
Why use I as variable name?! Review the loop condition.
