C Program To Print Sum of Series 1+1/2+1/4+1/8+…+1/n

Here, we have listed How To Print The Sum of Series of Numbers in the format 1 + 1/2 + 1/4 + 1/8 + … +1/n in C Programming Language. It is important that we should know about the How A For Loop Works before getting further with the C Program Code.

We have listed following Methods to Find The Sum of Sequence in C Programming:

  • Addition of Series without Function
  • Sum of Sequence with Function

In this C Program, we take a Limit as an Input from the user. Suppose, if the user enters the Limit as 5, the program will calculate the Sum of Series starting from Number 1 to 5.


1 + 1/2 + 1/4 + 1/8 + 1/16 = 1.9375
