{
int i,sum=0;

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

return(sum);
}

* Enter Value of N.
* Program will calculate sum from Number 1 to N and will return it to the calling function i.e. void main().
* Here we have crated function add() with one parameter its n, and return type as integer.
* In add() function we have created temporary variable which will automatically dispose when you exist from the function.
