int i,len=0;
char *b;
clrscr();

Answer / prakash

#include <stdio.h>

void reverse(char *str)
{
if (*str == '\0')
return;

reverse(str+1);

printf("%c", *str);
}

int main()
{
char str[50];

printf("Enter the string: ");
scanf("%s", str);

printf("Reversed string: ");
reverse(str);
printf("\n");

return 1;
}

Answer / right

char* reverseStringR(char* string){
if(string[0] && !string[1])
return string;

char first = string[0];

reverseStringR(string+1);
size_t length_rest = strlen(string+1);
memmove(string, string+1, length_rest);
string[length_rest] = first;

return string;
}
