C Program to find Sum of N Numbers using Recursion

C Program to find Sum of N Numbers using Recursion

The following C program using recursion displays the first N natural number on the terminal. The user enters the Nth number as the input, the program then displays all integral number starting from 1 up to the N.

    #include <stdio.h>

    void display(int);

    int main()

    {

        int j, result;

        printf("Enter the Nth number: ");

        scanf("%d", &j);

        display(j);

        return 0;

    }

    void display(int j)

    {

        static int i = 1;

        if (j == i)

        {

            printf("%d   \n", j);

            return;

        }

        else

        {

            printf("%d   ", i);

            i++;

            display(j);

        }

    }
