Need Help With Sub Procedures

I need help putting this program I have done that works correctly into Sub procedures.

Code:

---

#include<stdio.h>
#include<string.h> /* Needed To Do Copy, Reverse & Compare */

int main()
{
    /* Declare Variables */
   
    char vectorEntered[21]; /* Size = 21 because \0 takes up one space */
    char vectorBackwards[21]; /* Size = 21 because \0 takes up one space */

    /* Input From User */
   
    printf("\n Enter A Vector (String):= ");
    gets(vectorEntered);

    /* Changing The Vector, Backwards */
   
    strcpy(vectorBackwards,vectorEntered); /* Copy The Vector Entered to Vector Backwards */
    strrev(vectorBackwards); /* Reverse Vector Backwards */

    /* Compare The Vectors And Output Answer */
   
    if(strcmp(vectorEntered,vectorBackwards)==0) /* Compare The Two Variables A Sucess*/
    {
        printf("\n The Vector Entered, \"%s\", is the same forwards as backwards!",vectorEntered);
    }
    else /* Compare The Two Variables Not A Sucess */
    {
        printf("\n The Vector Entered, \"%s\", is not same forwards as backwards!",vectorEntered);
    }
   
    getchar();
    getchar();
    return 0;
}

This part below from the program i need in one sub procedure for the input:

Code:

---

    printf("\n Enter A Vector (String):= ");
    gets(vectorEntered);

---

I need another for:

Code:

---

    strcpy(vectorBackwards,vectorEntered); /* Copy The Vector Entered to Vector Backwards */
    strrev(vectorBackwards); /* Reverse Vector Backwards */

---

I also need one for:

Code:

---

    if(strcmp(vectorEntered,vectorBackwards)==0) /* Compare The Two Variables A Sucess*/
    {
        printf("\n The Vector Entered, \"%s\", is the same forwards as backwards!",vectorEntered);
    }
    else /* Compare The Two Variables Not A Sucess */
    {
        printf("\n The Vector Entered, \"%s\", is not same forwards as backwards!",vectorEntered);
    }

Please Help, I dont know how to make sub procdures work properly in this program.

I have also attached the program as well.

If you don't know how to write a function, then I suggest you get a book and Learn C.
This is not a "Do my assignments for me" forum.

Well aside from using gets() at all, you're using a C++ compiler to compile C

Call it getInput(vectorEntered)

Say
CopyAndReverse(vectorBackwards,vectorEntered)

> ...
Maybe
CompareAndPrint(vectorBackwards,vectorEntered)

Code:

---

    getchar();
    getchar();

A better way to do this would be to read http://faq.cprogramming.com/cgi-bin/...&id=1043284392 and come up with

Code:

---

int c;
while((c = getchar()) != '\n' && c != EOF);
while((c = getchar()) != '\n' && c != EOF);
