Struct array string merge with another string in c

So i have a problem where the string in struct merge with another array. See the code and output for more explanation. Code:

#include <stdio.h>
#include <stdlib.h>

struct print
{
    char code[3];
    char name[10];
}test[2]={"001","Alen","101","Paul"};

int main()
{

    int x;
    for(x=0;x<2;x++)
    {
        printf("%s %s\n",test[x].code,test[x].name);
    }
    return 0;
}

Output:

001Alen Alen
101Paul Paul

Process returned 0 (0x0)   execution time : 0.017 s
Press any key to continue.

The output is wrong, it should be like this:

001 Alen
101 Paul

So why the "name" merge in "code" variables? It shouldn't be like that. So how do i solve this? Thank you.

Solution

  • C strings need to be NUL terminated. Your code array field is one character too small. Change char code[3]; to be char code[4];
