How to reverse a string using a recursive function, with swapping?..

Answer / vignesh1988i

#include<stdio.h>
#include<conio.h>
char a1[50]; //GLOABAL VAR.
void reverse(int);
void main()
{
int count=0;
printf("enter the string :");
scanf("%s",a1);
for(int i=0;a1[i]!='\0';i++)
count++;
reverse(count);
getch();
}

void reverse(int count1)
{
char temp;
static int i=0;
if(i<=count1/2)
{
temp=a1[i];
a1[i]=a1[count1-1];
a1[count1-1]=temp;
i++;
reverse(--count1);
}
else
printf("\nthe reversed string is :%s",a1);
}

Answer / vignesh1988i

my next logic:::

#include<stdio.h>
#include<conio.h>
void reverse(char*,char*);
void main()
{
char a1[50],*p;
int count=0;
printf("enter the string:");
scanf("%s",a1);
for(int i=0;a[i]!='\0';i++)
count++;
p=a1+(count-1);
reverse(a1,p);
printf("the reversed one is : %s",a1);
getch();
}
void reverse(char *a1,char *p)
{
char temp;
if(a1<=p)
{
temp=*a1;
*a1=*p;
*p=temp;
reverse(++a1,--p);
}
}

thank u

Answer / vignesh1988i

the corrected code is:::

#include<stdio.h>
#include<conio.h>
char a1[50]; //GLOABAL VAR.
void reverse(int);
void main()
{
int count=0;
printf("enter the string :");
scanf("%s",a1);
for(int i=0;a1[i]!='\0';i++)
count++;
reverse(count);
getch();
}

void reverse(int count1)
{
char temp;
static int i=0;
if(i!=count)
{
temp=a1[i];
a1[i]=a1[count1-1];
a1[count1-1]=temp;
i++;
reverse(--count1);
}
else
printf("\nthe reversed string is :%s",a1);
}
