Question: 2 / 10

write a program to reverse the linklist.

struct node * reverseList ( struct node *current, struct node *prev)
{
struct node *tmp = current->next;
current->next = prev;
if (tmp !=NULL)
reverseList(tmp, current);

return current;
}

Question: 3 / 10

write a program to reverse all the word in given sentence .
Ex. India is a Great Country.
Output: aidni si a taerg yrtnuoc.

reverseWordString ( char * str)
{
int len, i, j;
len = strlen(str);
j = 0;
for (i = 0;i < len; i++)
if ( str[i] == ' ')
{
swap (str, j, i-1)
j = i+1;
}

void swap(char *str1, int start, int end)
{
int i = start;
char tmp;
for ( ; i<=end; i++, end--)
tmp = srt1[i];
str1[i]= str[end];
str[end] = tmp;
}

Question: 4 / 10

write a program to set the nth bit .

void setNthbit (int num, int bitposition)
{
num |= (1 << bitposition);
}

Question: 5 / 10

Write your own printf.

Question: 6 / 10

write your own strncpy.

void owncpyString ( char const *str , char *rev, int length )
{
int i ;

for ( i = 0; (i < length && str[i] != '\0'); i++)
rev[i] = str[i];
if (i < length)
for ( ; i < length; i++)
rev[i] = '\0';

}
