C Programlama Örnek IV

Klavyeden okunan seri numarasına göre PI = 4- 4/3 + 4/5 – 4/7 + 4/9 - 4/11 + ... serisinden PI yi hesaplayan program

1. terim 4
2. terim 2.666666 (4 -4/3)
3. terim 3.466666 (4 -4/3 +4/5)

Cevap:

#include

int main()

{

           float serino,toplam=0,payda=1;

               int i=1;

                  scanf("%f",&serino);

                  for(i=1; i<=serino; i++)

                  {

                        if(i%2==0)

                             toplam-=4/payda;

                        else

                             toplam+=4/payda;

                        printf("%d. terim : %fn",i,toplam);

                        payda+=2;

                  }

}
