c while ile girilen sayıların ortalamasını bulma:

#include <stdio.h>

int main()
{
    int count, sayi, not, toplam, ortalama; 

    toplam = 0; 
    printf( "Girilecek sayı adetini giriniz: " ); 
    scanf( "%d", &count );
    sayi=1;
   
    while ( sayi <= count ) { 
       printf( "%d. sayiyi giriniz: ",sayi ); 
       scanf( "%d", &not );
       toplam = toplam + not;
       sayi = sayi + 1; 
    }
    ortalama = toplam / count;
    printf( "Ortalama %d dir.\n", ortalama );
    return 0;
}

çıktı:

Girilecek sayı adetini giriniz: 3                                                                                                                                                  

1. sayiyi giriniz: 1                                                                                                                                                               

2. sayiyi giriniz: 2                                                                                                                                                               

3. sayiyi giriniz: 3
