Custom gets and puts functions

Hi,
I am writing custom gets() and puts() functions. I have started like this but got stuck as i didnt know to store the char.... I think the code will tell you where i am stuck

Code:

---


#include <stdio.h>
#include <string.h>

void xgets(char *str);

char str1[100];

int main()
{
        char str[100];

        printf("Enter a string");
        xgets(str);
        printf("%s",str);

        return 0;

}

void xgets(char *str)
{
        while(*str!='\n')
        {

---

well that was for gets

and this is for puts

Code:

---


#include <stdio.h>
#include <string.h>

void xputs(char *str);


int main()
{
        char str[100];

        printf("Enter a string");
        gets(str);
        xputs(str);


        return 0;

}


void xputs(char *str)
{
        while(*str!='\0')
        {
                printf("%c",*str);
                str++;
        }
}

---

this one works if a string is passed to puts. But if puts is like this then i dont know how to get it working.

puts("Print this");

Hope i am clear with my question.

Please help.

I'm not sure what the problem really is here. Is this the fix?

Code:

---

void xputs (const char * putMe)
{
 while (*putMe != '\0')
 {
  ...

---

Incidentally, puts prints a newline after printing the string.

Code:

---

#include <stdio.h>
#include <string.h>
#include <conio.h> // getche() ... you have to get input from the keyboard some how

#define ENTER    0x0D  // Enter Key
#define BACKSPACE 0x08  // Backspace key
#define TRUE        1
#define FALSE      0

void xputs(char *str)
{
        int idx = 0;

        printf("\n");

        while(str[idx] != NULL)
        {
                printf("%c",str[idx]); // take the * off
                idx++;
        }
}

void xgets(char * str)
{
        int idx = 0, i = 0;

        //Get the number of chars/subscripts
        while( str[idx] != NULL )
                idx++;

        // Force the chars/subscripts to be NULL
        for( i = 0; i < idx; i++ )
                str[i] = NULL;

        // re/assign stuff here
        idx = 0;

        while(TRUE)
        {
                str[idx] = getche(); // getche() returns the key pressed

                if(str[idx] == ENTER)
                        break;

                idx++;
        }
}

int main()
{
        char str[100];

        printf("Enter a string : ");
        //gets(str); printf("%s",str);

        xgets(str);

        // 1st way of puts()
        xputs(str);

        // 2nd way of puts()
        xputs("My puts function");

        return 0;

}

There are some problems with this code, for i didn't spend much time with it. I hope this gives you some ideas.
