Reverse A String

Program to reverse a string into another using a user-defined function (i.e. without using string handler function)

#include<stdio.h>

#include<conio.h>

main()

{

  char s1[25],s2[25];

  int x,count=0;

  char reverse(char[],int,char[]);

  clrscr();

  printf("Enter your string: ");

  gets(s1);

  for(x=0;s1[x]!='\0';x++)

    count++;

  reverse(s1,count,s2);

  printf("\nReversing your string...\n");

  puts(s2);

  return 0;

}

char reverse(char a[25], int len, char b[25])

{

  int i=len-1,j=0;

  while(i>=0)

    b[j++]=a[i--];

  b[j]='\0';

  return *b;

}
