This is the program for additiion of n consecutive numbers starting from 1.

You cannot add any number.

The recursion program to add consecutive n numbers starting from 1 (without using static variables):

int getSum(int n)

{

if(n == 1)

return 1;

return (n + getSum(n-1));

}

int main(){

int n,sum;

printf("Enter the value of n: "); scanf("%d",&n);

sum = getSum(n);

printf("Sum of n numbers: %d",sum);

return 0;

}

@Anonymous your code does not work with negative numbers:

better getSum function would be to add if block:

int getSum(int n)

{

if(n == 1)

return 1;

else if(

return (n + getSum(n-1));

}

mine too, it works only for non negative numbers, i mean we cannot get sum of negative numbers from my algorithm.

could you please tell me if my code will work as well? or what is side effects that I wrote 0 and you guys 1

int additionOfNumbers(int n){

if(n==0){

return 0;

}

return n+additionOfNumbers(n-1);

}
