Thread: simple Recursion program - strange output

i want to write program which prints all natural numbers from 1 to n.
where n is user input. but i want to write using recursion and not by for loop.
ex. if user enters 5 then output should be 1 2 3 4 5
i tried following code but its not working.

Code:

#include <stdio.h>#include <stdlib.h>


int main()
{
    int n;
    printf("enter no.");
    scanf("%d", &n);
    rec(n);
    return 0;
}


int rec(int n) {
    if(n==1) {
        printf("1\n");
    }
    else {
            n--;
            printf("%d\n",rec(n));
    }
}

the output is 1 0 2 2 2....upto n.

please help me and can anyone tell me whats the mistake in this code
thanks
