change the following statement:
scanf("%s",vnaam[50])
with
scanf("%s",vnaam)

You don't need to specify the array index when writing to it:
#include <stdio.h>
#include <conio.h>
int main (void)
{
 char vnaam[50];
printf("Wat is u voornam ?");
scanf("%s",vnaam);
getchar();
printf("well look %s",vnaam);
getchar();    
}

fyi - vnaam[50] in the scanf is simply the 51st entry into the vnaam array.
But since you define vnaam[50] to have only 50 entries, then you are actually referencing a char that is outside of the array. In some instances, your program will crash with a segment fault if you do this.

thanks my code looks like this

i have another question what if i dont know how long the array will be, now its 50 but can just leave it blank ?



#include <stdio.h>
#include <conio.h>
int main (void)
{
 char vnaam[];
printf("Wat is u voornam ?");
scanf("%s",vnaam);
getchar();
printf("well look %s",vnaam);
getchar();    
}

>> char vnaam[];
Sorry, this is not valid. If you are filling up an array with scanf, you should make it much larger than any possible entry. After the entry, it will be null terminated.

I don't think you can. Normally you would size the char[] to the maximum size you were expecting.

#define MAX_STRING_SIZE 80

int main()
{
    char[MAX_STRING_SIZE] buffer;

    // scanf, etc, etc
}

To protect from overflow, you should consider using fgets which limits the number of chars transferred to the buffer. (In this case, from the console, you would use stdin as the file handle.)

But read this carefully w.r.t. newline char and null termination.

I'm not sure about scanf function but I remember that cin function in C++ takes 512 characters, not more.
