Hi , I have to write a program that calculates the number of possible combinations k of n objects.
It has to be a recursive program.
It compiles and runs, but while debugging while I type in some numbers it returns 0 everytime
Thanks for any help
Code:
#include <stdio.h>
int possibleCombi(int n,int k);
int main (void)
{
int n,k,combinations;
printf("type in n , number of total objects");
scanf("%d",&n);
printf("type in k , numbers drawn");
scanf("%d",&k);
combinations = possibleCombi(n,k);
printf("%d",combinations);
}
int possibleCombi(int n,int k)
{
if ((k = 0) || (n = k)){
return 1;
}
if(n > k > 0){
return (possibleCombi(n - 1,k) + possibleCombi(n - 1,k - 1));
}
}
