C language: Using pointer variables, the function implementation of the 3 integers in order from large to small output

Using pointer variables, the function implements the output of 3 integers in order from large to small.

Solution: Program:

#include <stdio.h>

void swap (int *ptr1, int *ptr2)

{

int temp = *PTR1;

*PTR1 = *PTR2;

*PTR2 = temp;

}

void Exchange (int *q1, int *q2,int *q3)

{

void swap (int *ptr1, int *ptr2);

if (*q1 < *Q2)

{

Swap (Q1, Q2);

}

if (*q1 < *Q3)

{

Swap (Q1, Q3);

}

if (*q2 < *Q3)

{

Swap (q2, Q3);

}

}

int main ()

{

void Exchange (int *q1, int *q2, int *q3);

int *P1, *P2, *p3, A, b,c;

printf ("Please enter three integer numbers:");

scanf ("%d,%d,%d", &a,&b,&c);

P1 = &a;

P2 = &b;

P3 = &c;

Exchange (P1, p2, p3);

printf ("The Order is:%d,%d,%d\n", a,b,c);

return 0;

}

Results:

Please enter three integer numbers:7,-9,666

The Order is:666,7,-9
