find the smallest number of a array?

main()
{
int a[20],n,i,s;
scanf("%d",&n);
for(i=0;i<n;i++)
{
scanf("%d",&a[i]);
}
s=a[0];
for(i=0;i<n;i++)
{
if(s>a[i])
{
s=a[i];
}
}
printf("the smallest number is %d",s);
}

#include<conio.h>
void main()
{
int n,a[50],temp;
printf("enter the max limit :");
scanf("%d",&n);
for(int i=0;i<n;i++)
scanf("%d",&a[i]);
i=0;
for(int j=0;j<n-1;j++)
{
if(a[j+1]<a[j])
{
temp=a[j+1];
a[j+1]=a[j];
a[j]=temp;
}
}
printf("the smnallest is : %d",*(a+0));
getch();
}
