  char name[25];
  char temp[25];
  char  *ptr;
  int temp1;
  char b;
  
  printf("please enter name  ");
  gets(name);
  ptr=strlen(name);

Answer -
Here is the corrected code:
#include <stdio.h>

main()
{
       char name1[25], name2[25];
       char temp[25];

       printf("please enter name1 => ");
       gets(name1);
       printf("please enter name2 => ");
       gets(name2);

       printf("Before swap:\n");
       printf("Name1 => %s\n", name1);
       printf("Name2 => %s\n", name2);

       strcpy(temp, name1);
       strcpy(name1,name2);
       strcpy(name2, temp);

       printf("After  swap:\n");
       printf("Name1 => %s\n", name1);
       printf("Name2 => %s\n", name2);
}

Answer
So, what is the complete problem statement?
You must use pointers and you should not use malloc!?
Is that right?

And are you allowed to use, any number of temporary variables?

If you make your problem statement clear, we can try to get the correct solution.
