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

Method 1: Find Addition of Series without using Function in C
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 | #include<stdio.h> int main() { float sum = 0.0, j = 1.0; int count, limit; printf("\nThe Sum of Series 1+1/2+1/4+1/8...+1/n \n"); printf("Enter The Limit:\t"); scanf("%d", &limit); for(count = 1; count <= limit; count++) { sum = sum + (1/j); j = j * 2; } printf("\nSum of Series:\t %f", sum); printf("\n"); return 0; } |

Method 2: Calculate Addition of Series using Function in C
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 | #include<stdio.h> float sum_cal(int limit); int main() { float res; int limit; printf("\nThe Sum of Series 1+1/2+1/4+1/8...+1/n \n"); printf("Enter The Limit:\t"); scanf("%d", &limit); res = sum_cal(limit); printf("\nSum of Series:\t %f", res); printf("\n"); return 0; } float sum_cal(int limit) { float sum = 0.0, j = 1.0; int count; for(count = 1; count <= limit; count++) { sum = sum + (1/j); j = j * 2; } return sum; } |

Best Descriptive Program I Found!!
Thanks Mahesh. Here, at CodingAlpha we focus on providing perfectly working and executable programs to students.
I really dont understand these pattern codes for finding sum of series in C programming. I only need it for mh college assignments. 🙂
Can I know how to add the series of
1+(1+2)+(1+2+3)+….+(1+2+….+n)
