Answer:-

The code for above program is given below, i have commented in line for explanation.

Code:-

#include <stdio.h>

int main()
{
int a,b,c,d;
printf("Enter four numbers: ");
scanf("%d%d%d%d",&a,&b,&c,&d);
  
// variable to store maximum value
int max;
  
// compare a with b,c,d
if((a>b) && (a>c) && (a>d))
// store a in max
max = a;

// compare b with a,c,d
if((b>a) && (b>c) && (b>d))
// store b in max
max = b;

// compare c with b,a,d
if((c>a) && (c>b) && (c>d))
// store c in max
max = c;

// compare d with b,c,a
if((d>a) && (d>b) && (d>c))
// store d in max
max = d;

// variable to store minimum value
int min;
  
// compare a with b,c,d
if((a<b) && (a<c) && (a<d))
// store a in min
min = a;
  
// compare b with a,c,d
if((b<a) && (b<c) && (b<d))
// store b in min
min = b;
  
// compare c with b,a,d
if((c<a) && (c<b) && (c<d))
// store c in min
min = c;
  
// compare d with b,c,a
if((d<a) && (d<b) && (d<c))
// store d in min
min = d;
  
printf("Greatest is %d and smallest is %d",max,min);
return 0;
}

Output:-

Enter four numbers: 2 10 -97 Greatest is 10 and smallest is -9 ... Program finished with exit code 0 Press ENTER to exit console.
