تكفون يا طلاب احمد الملحم 103 ؟

السلام عليكم و رحمة الله و بركاته.

تفضل:

السؤال الأول:

كود:

#include <stdio.h>

void sum_n_avg(double n1, double n2, double n3, double *sum, double *average);

int main(void)

{
 
 double n1, n2, n3, sum, average;
 
 printf("Enter Three Numbers Seperated By Spaces=> ");
 
 scanf("%lf%lf%lf", &n1, &n2, &n3);
 
 sum_n_avg(n1, n2, n3, &sum, &average);
 
 printf("\nThe Sum Of The Entered Numbers Is %.2f.\n\n", sum);
 
 printf("The Average Of The Entered Numbers Is %.2f.\n\n", average);
 
 system("PAUSE");
 
 return 0;
    
}

void sum_n_avg(double n1, double n2, double n3, double *sum, double *average)

{
 
 *sum = n1 + n2 + n3;
 
 *average = *sum / 3;
      
}

السؤال الثاني:

كود:

#include <stdio.h>

int find_sum(int n);

int main(void)

{
 
 int n;
 
 printf("Enter An Integer (Bigger Than Zero)=> ");
 
 scanf("%d", &n);
 
 do
 
 {
  
  if(n < 1)
  
  {
   
   printf("\nError: The Integer You've Entered Is Not Bigger Than Zero; Try Again=> ");
   
   scanf("%d", &n);
        
  }
                
 }
 
 while(n < 1);
 
 printf("\nThe Sum Of The Integers From 1 To %d Is %d.\n\n", n, find_sum(n));
 
 system("PAUSE");
 
 return 0;
    
}

int find_sum(int n)

{
 
 int sum;
 
 sum = 0;
 
 if(n == 1)
 
 sum = sum + 1;
 
 else
 
 sum = sum + n + find_sum(n - 1);
 
 return sum;
    
}

مع السلامة.
