this is my code i try to make a program but the code didn't work for me

[samimmu]

this is my code i made this code because to reverse the words and get the number or frequent characters.this my code below.

#include <iostream>
#include <cstring>
using namespace std;

void reverse(char *str, int count = 0);

int main()
{
  char *s1 = "This is a taste for you";
  char *s2 = "i like her smile her delicate talk i like her.";

  reverse(s1); // reverse entire string
  reverse(s2, 50);  // reverse 1st 7 chars

  cout << s1 << '\n';
  cout << s2 << '\n';

  return 0;
}

void reverse(char *str, int count)
{
  int i, j;
  char temp;
  
  if(count == 0) count = strlen(str)-1;

  for(i = 0, j=count; i < j; i++, j--) {
    temp = str[ i ];
    str[ i ] = str[j];
    str[j] = temp;
 }
}

so the question ask me to input character, reverse the characters and get the number or frequent numbers. i am really grateful for you if you can help me, i need you to correct that post and send me back the code actually the due date is next friday.

So what do you need help with?

Is it reversing the strings correctly? Did you have to add anything?

[samimmu]

thanks friend for responding. actually i try to compile it but it didn't work,besides that i want the input to be any kind of character, i don't want to specify the inputs,i want the use to input any words.as u can see in the code, i wish you can help in this case,thank you very much

It compiles with VS…

But your assigning char pointers to constant char[]. If you try and edit the string, it wont work. You need to do something like:

#include <iostream>
#include <cstring>
using namespace std;

void reverse(char *str, int count = 0);

int main()
{
  char s1[] = "This is a taste for you";
  char s2[] = "i like her smile her delicate talk i like her.";

  reverse(s1); // reverse entire string
  reverse(s2, 7);  // reverse 1st 7 chars

  cout << s1 << '\n';
  cout << s2 << '\n';

  return 0;
}

void reverse(char * str, int count)
{
	int i, j;
	char temp;
  
	if(count == 0)
	{
		count = strlen(str)-1;
	}

	for(i = 0, j=count; i < j; i++, j--) 
	{
		temp = str[i];
		str[i] = str[j];
		str[j] = temp;
	}
}

And if you really want to use pointers, you could do this:

#include <iostream>
#include <cstring>
using namespace std;

void reverse(char *str, int count = 0);

int main()
{
  char *s1 = new char[100];
  char *s2 = new char[100];

  strcpy(s1,"This is a taste for you");
  strcpy(s2,"i like her smile her delicate talk i like her.");

  reverse(s1); // reverse entire string
  reverse(s2, 7);  // reverse 1st 7 chars

  cout << s1 << '\n';
  cout << s2 << '\n';

  delete s1;
  delete s2;

  return 0;
}

void reverse(char * str, int count)
{
	int i, j;
	char temp;
  
	if(count == 0)
	{
		count = strlen(str)-1;
	}

	for(i = 0, j=count; i < j; i++, j--) 
	{
		temp = str[i];
		str[i] = str[j];
		str[j] = temp;
	}
}

thank you very much, it works as i want .thanks a lot....
