Write a program in ‘C’ language to reverse an input string
#include<stdio.h>
#include<conio.h>
struct list
{
char ch;
struct list *next;
}*top=NULL;
/*store string to stak*/
void push(char s)
{
struct list* t;
t=(struct list*)malloc(sizeof(struct list));
t->ch=s;
t->next=top;
top=t;
}
/*display reverse string*/
void display()
{
struct list *tmp;
tmp=top;
while(tmp!=NULL){
printf("%c",tmp->ch);
tmp=tmp->next;
}
}
main()
{
char c;
clrscr();
printf("enter a stringn");
while(c!='n')
{
c=getchar();
push(c);
}
printf("reversed string isn");
display();
getch();
}
