Let us play with time:
write a program to find index of smallest no in an array?

The one whose program will take minimum execution time and with smallest exe file size will be appreciated
😀

Compiler used - Visual C++ Express 2008.

Here is the code.

#include "stdafx.h"

int main ()
{
    int arr[] = {5, 9, 2, 4, 5, 3, 9, 6, 7, 4};
    int smallest = arr[0];
    int index, i;
    for (i = 0; i < 10; i++)
    {
        if (arr[i] <= smallest)
        {
            smallest = arr[i];
            index = i;
        }
    }
    printf ("The smallest element in the array is %d and its index is %d\n", smallest, index);
    return 0;
}

I think size of executable may vary with the compiler used.
Size of this exe when compiled using VC++ 2008 is 30 Kb.

correct .let us wait for more answers ..by the way have you checked run time of this program?

I don't know about visual c++ but you can check it in turbo c++

click on option 'compile' in menu bar...then click 'information'

For more info have a look of this thread

Well, I couldn't find that in VC++. Even googling didn't help much.

#include<iostream>
using namespace::std;
int main()
{
int a[10]={5, 9, 2, 4, 5, 3, 9, 6, 7, 4},i,n,index;
n=a[0],index=0;
for(i=1;i<10;i++)
if(a<n) n=a, index=i;
cout<<index;
return 0;
}

This code has executible file of size 464 kb in dev-cpp and 24 kb in turbo c, also the code has 0.1 millisecond execution time in Turbo, dont know how to find time in dev-cpp
