#include <stdio.h>
#include <conio.h>
**void** main
{
**int** n;
**int** num[100];
**int** L;
**int** desnum[100], k;
**int** i, i, temp;
printf("\nEnter the total number of marks to be entered: ");
scanf("%d",&n);
clrscr();
**for**(L=0;L<n;L++)
{
printf("\n Enter the marks of student %d : ", L+1);
scanf("%d",&num[L]);
}
**for**(k=0;k<n;k++)
{
desnum[k]= num[k]
}
**for**(i=0;i<n-1;i++)
{
**for**(j = i+1; j<n; j++)
{
**if**(desnum[i]<desnum[j])
{
temp = desnum[i];
desnum[i]= desnum[j];
desnum[j]= temp;
}
}
}
**for**(i=0;i<n;i++)
printf("\nNumber at [%d] is %d", i, desnum[i]);
}

Can you tell me effection of this section

Code:

**for**(k=0;k<n;k++)
{
desnum[k]= num[k]
}
