lowest variable

I have 5 numbers and each is stored in its own variable. How do I find the lowest number?

Hint: Make an array of pointers, then loop through it to find the lowest.

Code:

---

int a[5];
a[0]=23;
a[1]=13;  ..... etc
printf("%d\n",min(a,5) );
...............
int min(int *whatever,int cnt){

      int *ptr;
      int result=0  // assume all numbers are positive
      for(ptr=whatever;cnt;cnt--,ptr++)
                          if (*ptr>result) result=*ptr;
      return result;
           
}

:D

min is not a good choice for the name, there is a macro with that name.

In C++ you can use the min_element algorithm.

For parksie's suggestion, here's what you would do (in C++):

Code:

---

#include <algorithm>
using std::min_element;

int a, b, c, d, e; // your 5 integers
// parksie's suggestion:
int * ar[5] = {&a, &b, &c, &d, &e};
// my suggestion:
struct pred_minptr {
  bool operator ()(int *pa, int *pb) {
    return *pa < *pb;
  };
};

// find the minimum:
int min = **min_element(ar, ar+5, pred_minptr());
