hi guys


i cant run the c++ and i have H.W yo submet
i want someone to check if the answer is correct

this is the question
Write a C-Program that does the following
Read integer numbers from a file inp.dat
Calculate the sum, average, and multiplicand of even numbers and store the result and the even numbers in output file out1.dat
Calculate the sum, average, and multiplicand of odd numbers and stored the result and the odd numbers in output file out2.dat



answer
Code: C
#include <stdio.h>
#include <math.h>
#include<stdlib.h>
main ()
{
    FILE        *inp,*outp1,*outp2    ;
    int         num,even_sum,odd_sum,even_product,odd_product,count_even=0,count_odd=0;
    double      even_average,odd_average   ;
   
   
   
    inp=fopen("C:\grades.txt","r");
    outp1=fopen("C:out1.txt","w");
    outp2=fopen("C:out2.txt","w");
   
   
    if(inp==NULL)
    {
        printf("cannot open file");                               
        exit(1) ;
    }
   
   
    even_sum=0   ;
    even_product=1;
    odd_sum=0;
    odd_product=1;
   
    for(fscanf(inp,"%d",num);num!=EOF;fscanf(inp,"%d",num));
    {
        if(num%2==0)
        {
            fprintf(outp1,"even=%d\n",num);
            even_sum+=num   ;
            even_product*=num
                count_even ++;
        }
       
       
        else
        {
            fprintf(outp2,"odd=%d\n",num);
            odd_sum+=num  ;
            odd_product*=num  ;
            count_odd ++;
        }
       
    }
   
    even_average=(even_sum)/count_even  ;
    odd_average=odd_sum/count_odd  ;
   
    fprintf(outp1,"the sum=%d\n the product=%d\n and the average=%lf",even_sum,even_product,even_average);
    fprintf(outp2,"the sum=%d\n the product=%d\n and the average=%lf",odd_sum,odd_product,odd_average);
}
