Answer / patrck

//check this program....

#include <string.h>
#include <stdio.h>
main(){
char a[100],b[100];
int i,j=0,c=0,k,cnt=0;
printf("enter the sentence\n");
for(i=0;i>=0;i++){
a[i]=getchar();
if(a[i]=='\n')break;
}
for(i=0;a[i]!='\n';i++)
cnt++;
for(i=0;i<(cnt+1);i++)
b[i]=' ';
for(i=0;i<(cnt+1);i++){
c++;
if((a[i]==' ')||(a[i]=='\n')){
c=c-1;
for(j=(cnt-i),k=(i-c);c>0;k++,j++,c--){
b[j]=a[k];
}c=0;
}
}
printf("result: ");

Answer / manish

int i, j, k;
int t = 0;

char[] c = "manish singhal is here".ToCharArray();

j = c.Length;
char[] b=new char[c.Length];

for (i = c.Length - 1; i >= 0; i--)
if ((i > 0 && c[i - 1] == ' ') || i == 0)
{
for (k = i; k < j; k++)
b[t++] = c[k];
if (i > 0)
b[t++] = c[--i];
j = i;
}
Console.WriteLine(b);
Console.ReadLine();

Answer / ashish

this works in O(n) as first reverse all the sentence....then
reverse each word....


#include<iostream.h>
#include<conio.h>
#include<string.h>

char a[50];

void wrd_reverse()
{
void str_rev(int start_index,int len);
int t=strlen(a);
str_rev(0,t);
int i=0;int st_indx=0;int count=0;
int size;
while(a[i]!='\0')
{
if(a[i]!=' ')
count++;
else
{

size=count;
str_rev(st_indx,size);
count=0;
st_indx=i+1;
}
i++;
}
size=count;
str_rev(st_indx,size);

}

void str_rev(int start_index,int len)
{
int sft=start_index;
int lenm=len/2;
len--;
for(int i=0;i<lenm;i++)
{
a[sft+i]=a[sft+i]+a[(sft+len)-i];
a[(sft+len)-i]=a[sft+i]-a[(sft+len)-i];
a[sft+i]=a[sft+i]-a[(sft+len)-i];
}
}

int main(){
cin.getline(a,40);
void wrd_reverse();
wrd_reverse();
cout.write(a,40);
return 0;

}

Answer / sujan

previously i hav read the question mistake so i hav jst given to reverese the whole sntence not a particular word so this one program will give u final ans....test this program...and if u hav any question please ask my through my emailid :sujan_faith@hotmail.com


#include<iostream>
using namespace std;
int main()
{
char str[]="sujan is name my haha";

string ans;

int n=0,j=0,t=0,a=0;
while (str[n]!='\0')
n++;
char temp[n];
char tem[n];
// cout<<n<<endl;
for(int i=n-1;i>=0;i--)
{
temp[j]=str[i];
j++;
if((str[i]==' ')||i==0)
{
// cout<<"i:"<<i<<endl;
// cout<<"j:"<<j<<endl;
for(int k=j-1;k>=t;k--)
{
tem[a]=temp[k];
a++;


}
t=a;



}
}
tem[a]='\0';
// temp[j]='\0';

// cout<<temp<<endl;
cout<<tem<<endl;
system("pause");
