Assign multiple values to array in C

Question

Is there any way to do this in a condensed form?

GLfloat coordinates[8];
...
coordinates[0] = 1.0f;
coordinates[1] = 0.0f;
coordinates[2] = 1.0f;
coordinates

typedef struct{
  char array[4];
}my_array;

my_array array = { .array = {1,1,1,1} }; // initialisation

void assign(my_array a)
{
  array.array[0] = a.array[0];
  array.array[1] = a.array[1];
  array.array[2] = a.array[2];
  array.array[3] = a.array[3]; 
}

char num = 5;
char ber = 6;

int main(void)
{
  printf("%d\n", array.array[0]);
// ...

  // this works even after initialisation
  assign((my_array){ .array = {num,ber,num,ber} });

  printf("%d\n", array.array[0]);
// ....
  return 0;
}
