How to display full name in C Programming?

[L3ir4]

I have tried the code below but it does not display the second name, only the first name. Everything else after the space is not being displayed.

#include<stdio.h>
main()
{
char name[20];

printf("name: ");
scanf("%s", name);

printf("\n%s", name);

getch();

}

The problem is that you are not reading the full name to begin with: %s format specifier for input stops reading at whitespace. You could consider the use of fgets instead, which also makes it somewhat easier to limit the number of characters read so as to avoid buffer overflow.

By the way, <conio.h> is non-standard (and you don't really need getch, so you can ditch it). I might have written instead:

#include<stdio.h>

int main(void)
{
    char name[20];

    printf("name: ");
    scanf("%s", name);

    printf("\n%s", name);

    return 0;
}

Notice the return type of main and the indentation.

You can take a look at How to get a line of text FAQ to see what Laser is saying about fgets().

And of course the main declaration.

As laserlight mentioned you can use the fgets() function. You could use this code to output your full name

#include <stdio.h>
#define MAX 20

int main(void)
{
    char name[MAX];
    char * ptr;

    printf("name?\n");
    ptr = fgets(name, MAX, stdin);
    printf("Your name is %s\n", ptr);

    return 0;
}
