Two C
functions sortInDescend_1() and sortInDescend_2() are
given. sortInDescend_1() is used for
call-by-value and sortInDescend_2() is
used for call-by-reference.

Please write a C program which does the following:
Given that variables a1 =
3, a2 =
1, a3 = 2, one example output is shown
below.
For example:
code
#include<stdio.h>
#include<string.h>
void swap(int *i,int*j)
{
int temp;
temp=*i;
*i=*j;
*j=temp;
}
void sortInDescend_1(int var1, int var2, int var3)
{
if(var1<var2){
swap(&var1,&var2);
}
if(var1<var3){
swap(&var1,&var3);
}
if(var2<var3){
swap(&var2,&var3);
}
}
void sortInDescend_2(int *var1, int *var2, int *var3)
{
if(*var1<*var2){
swap(var1,var2);
}
if(*var1<*var3){
swap(var1,var3);
}
if(*var2<*var3){
swap(var2,var3);
}
}
int main()
{
int a1,a2,a3;
scanf("%d",&a1);
scanf("%d",&a2);
scanf("%d",&a3);
sortInDescend_1(a1,a2,a3);//passing the values as it is
printf("a1: %d a2: %d a3: %d\n",a1,a2,a3);
sortInDescend_2(&a1,&a2,&a3);//passing the references
of the values, & symbol passes the address of the
variable
printf("a1: %d a2: %d a3: %d\n",a1,a2,a3);
return 0;
}
