C Program To Print Sum of Series 1+2+3+4+…+n
Here, we have listed How To Print The Sum of Series of Numbers in the format 1 + 2 + 3 + … + 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 + 2 + 3 + 4 + 5 = 15

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

Method 2: Calculate Sum of Sequence 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 | #include<stdio.h> int calc_sum(int x); int main() { int limit, res; printf("nThe Sum of Series 1+2+3+...+n n"); printf("Enter The Limit:t"); scanf("%d", &limit); res = calc_sum(limit); printf("nSum of Series:t %d", res); printf("n"); return 0; } int calc_sum(int x) { int count, sum = 0; for(count = 1;count <= x;count++) { sum = sum + count; } return sum; } |
