How to take user input return key?

So i am trying to make a talk program with vim. And i want to know how to take the return key input from the user and then let the program continue. I am doing this on a mac in Terminal btw.

Code:

---

#include <stdio.h>

main int()

{
  char name

 prinft("What is your name?");
 scanf("%c", &name);

 printf("Hello %c, how are you?", name);

 //then here i want to let the program only continue when the user has input the return key

 //for example the user can say: I am doing fine "return key"

 //and then the program continues

 printf("I am happy you are doing well, goodbye");
 return 0;

}

Thanks!

Use getch(0) to pause your program. It will continue when you hit any key.
If you want it to be the 'return' key' its a little more involved.

I'd advise you to look through some online examples about C-strings if you aren't using a textbook that teaches the language.

"%c" is the format specifier for characters. What you want is "%s", the format specifier for C-strings. Also, "char name;" is just one single character (like 'a', 'b' or 'p', etc). What you want is a character array (aka C-string). Something like "char name [5];" which could then be used to store 4 characters (say 'Z', 'e', 'u', 's', '\0') where '\0' is the string terminator.

No, do not use getch(). It's a non-standard function (and I think it's not supported by modern compilers). Also, getch() doesn't accept any parameters and so getch(0) won't compile.

The OP doesn't need getch() to "wait" for the user to press the enter key. Once the user types their name, they'd anyway have to hit enter so as to "submit" the input for the program to continue running.

Thanks guy's! The %s did the trick.

For the once's interested in this, here is my first talkbot :).

Code:

---

#include <stdio.h>


int main()
{


        char name[31];
        char lastname[31];
        char nothing[100];
        char feeling[100];
        char nothings[100];
        char ch[100];


        printf("Hi, what is your name?\n");
        scanf("%s", name);


        printf("Hello %s.\nHow are you doing?\n", name);
                       
                            scanf("%s", ch);
                               
                        printf("I see, how would you describe that in one word?\n");
                        scanf("%s", feeling);


                        printf("Feeling %s is one of the many feeling we all have sometimes.\nIs there anyhting else you want to share with me?\n", feeling);
                       
                        scanf("%s", nothings);
       
                        printf("Thank you for sharing %s. I hope the rest of your day will be very nice.\n", name);
                       
        return 0;
}

If you see some incorrect stuff im doing please let me know.

To be safe, you should limit the maximum number of characters in the scanf call, ie:

Code:

---

scanf("%30s", name);

---

It's one less than the size of the actual buffer to ensure room for the null terminator.
