Take sentence in an array and get array size and then print the array in ascending order.

I think what the question requires is that only the words in the sentence be reversed. For this follow this pseudo code:for each word in sentence: reverse (word)print reverse (sentence)for e.g. given 'an indian on road' after reversing each word we get 'na naidni no daro' on reversing this we get ' road on indian an'

Take the string in an array and continue loop till the half length of array and swap the characters which are at equals from both sides of array.

void main()


{


    char *s = "Life is beautiful", ch;


    int len = strlen(s), start, end = -1, t = 0, length = 0, i;


    clrscr();


    printf("Original sentence=%sn", s);


    *(s + len + 1) = '';


    *(s + len) = ' ';


    while (*(s + length) != NULL) {


        if (*(s + length) == ' ') {


            start = end + 1;


            end = length;


//printf("%d %dn",start,end);


            t = 0;


            for (i = start; i < start + (end - start) / 2 + 1; i++) {


                ch = *(s + i);


                *(s + i) = *(s + end - t);


                *(s + end - t) = ch;


                t++;


            }


        }


        length++;


    }


    strrev(s);


    printf("After processing=%s", s);


    getch();


}


 

This is a very simple program having following logic. Main string - Life is beautiful
After reversing words at their respective places - efiL si lufituaeb
Reversing it we get - beautiful is Life

A small code for this....

Code
#include


#include


#include


void main()


{


    int i, l;


    char s[] = "this is string reverse";


    clrscr();


    l = strlen(s);


    for (i = l; i >= 0; i--)


        printf("%c", s[i]);


    getch();


}

Hi Srinivas rao i think there is a small change required in ur program
coorect is
l=strlen(s)-1;

I think by using this code can do the reverse opeartion

Code
main()


{


    char c;


    if ((c = getchar()) != 'n')


        main();


    printf("%c", c);


    getch();


}

when u enter the 'enter key' it will terminate.

// A valid sentence is a group of words ended with a fullstop i.e.  with a dot( . ).
int main()
{

char sentence[50];
cin>>sentence;   //Every sentence must ended with a dot.

//print the sentence
for(int i=0; i!=' . ' ;i++)
cou<<sentence[i] ;


//reverse the sentence
int length= strlen(sentence);

// suppose the length of the sentence is 10 then fullstop is in the 10th position. For reversing the sentence we have to print from 10th-1 position to the 0th position.

for(int j=length-1; j>=0; j-- )
{
cout<<sentence[j];
}

return 0;

Hey srinivasarao,

You are not actually reversing the string !!
You are just printing the string in reverse order.

I think the question is revere the order of words in the sentence. Because reversing a sentence doesn't make a sense when you can simply copy one string to other in reverse order and do.

Here is what I did and it does reverse the order of spaces used in the sentence:

Code
 


 


#include <stdio.h>


char *reverse_word(char *s)


{


    char *str = s;


    int len = string_len(s);


    int i = 0;


    int count = 0;


    reverse_substring(str, 0, pos_lastChar(str));


    while (i <= len) {


        if (str[i] == ' ' || i == len) {


            reverse_substring(str, i - count, i - 1);


            count = 0;


        }


        if (str[i] != ' ') {


            count++;


        }


        i++;


    }


    return str;


}


 


int pos_lastChar(char *s)


{


    int i;


    for (i = string_len(s); i > 0; i--) {


        if (s[i] != ' ' && s[i] != '') {


            return i;


        }


    }


}


 


reverse_substring(char *s, int start, int end)


{


    char temp;


    int i, j;


    for (i = start, j = end; i < j; i++, j--) {


        temp = s[i];


        s[i] = s[j];


        s[j] = temp;


    }


}


 


int string_len(char *str)


{


    int x = 0;


    while (*str++) {


        x++;


    }


    return (x);


}


 


int main(int argc, char **argv)


{


    char str[] = "this is very beautiful";


    printf("nGiven String : %sn", str);


    printf("Length of string: %dn", string_len(str));


    printf("Reversed string: %sn", reverse_word(str));


    return 0;


}

Here is the code to reverse the sentence that does not use any in built string function. if the input is:Life is good output will be good is Life ;)

Code
 


#include<stdio.h>


void reverse(char *, char *);


int main()


{


    /*Declaration and initialization */


    char *begin = "Life is Good", *end, *start, *len, *space;


    start = begin;


    end = begin;


    /*Find length of string */


    printf("%s", start);


    len = begin;


    while (*len)


        len++;


    *len = ' ';


    *(++len) = '';


    len--;


 


    /*Reverse individual words */


 


    while (*end) {


        if (*end == ' ') {


            space = end;


            reverse(begin, end - 1);


            begin = space + 1;


            end = space;


        }


        end++;


    }


    *(--end) = '';


    /*Reverse the entire string */


    char *s1 = "";


    s1 = start;


    printf("


");


    reverse(start, len - 1);


    printf("%s", s1);


    return 0;


}


 


void reverse(char *begin, char *end)


{


    char *temp = "";


    while (end >= begin + 1) {


        *temp = *begin;


        *begin = *end;


        *end = *temp;


        end--;


        begin++;

I think you should use reverse string programme. You can store it an array and then run a loop.
