Please explain line no. 10, 12, 13

#1

min_index=i;
for(int j=i;j<=n-1;j++)
{
if(a[j]<a[min_index)
{
min_index=j;
}

please explain this as i am unable to understand it.

@Anku47 we are just keeping track of the index of smallest no in min_index
like array 4 2 3 1 0
min_index at first itr=0;
so after this loop min_index will be 4 as a[4]=0 smallest
