**Sum of 1 + 2 + …. + n series in c programming language**

#include<stdio.h>

int main(){

int n,i;

int sum=0;

printf("Enter
the n i.e. max values of series: ");

scanf("%d",&n);

sum
= (n * (n + 1)) / 2;

printf("Sum of
the series: ");

for(i =1;i <=
n;i++){

if (i!=n)

printf("%d +
",i);

else

printf("%d = %d
",i,sum);

}

return 0;

}

**Sample output:**

Enter the n i.e. max values
of series: 5

Sum of the series: 1 + 2 + 3
+ 4 + 5 = 15

**Mathematical Formula:**

Sum of the series 1 + 2 + 3
+ … + n = n (n+1)/2

Write a C program which will find the sum of the N-terms of the below

series. The program will consist of a MAIN function and a function.

2^n/n

Within the MAIN function.

• Number of terms N will be read from the standard input.

• N will be passed to the function as an argument.

• Sum of the N terms(return value from the function) will be printed.

Within the function.

• Sum of the N terms of the given series will be calculated and returned

to the MAIN function.

A Pascal number is a number that is the sum of the integers from 1 to j for some j. For example 6 is a Pascal number because 6 = 1 + 2 + 3. Here j is 3. Another Pascal number

is 15 because 15 = 1 + 2 + 3 + 4 + 5. An example of a number that is not a Pascal number is 7 because it falls between the Pascal numbers 6 and 10

Write a function named isPascal that returns 1 if its integer argument is a Pascal number,

otherwise it returns 0.

The signature of the function is

int isPascal (int n)
