in the Learn section I believe the code is wrong…

``````  struct Bottle {
char* name;
int maxCapacity;
int currentCapacity;
}

struct Bottle myBottle = {"Medium Bottle", 24, 0};

// Fill some of myBottle
myBottle.currentCapacity = "10";
printf(“The bottle is now filled to %d”, myBottle.currentCapacity);
``````

i think it should be:

``````myBottle.currentCapacity = 10;
``````

since its an int

hi,

I am practicing structure initialization with both methods:

``````#include <stdio.h>

void main() {

struct Airplane {
char type[5];
int maxAltitude;
int maxSpeed;
int maxRange;
};

//First method to initialize
struct Airplane dr400 = {"b", 15500, 166, 700};

//Second method
struct Airplane cesna172;
cesna172.type = "r";
cesna172.maxAltitude = 13500;
cesna172.maxSpeed = 163;
cesna172.maxRange = 700;

}
``````

The compiler throw me a error in the second method on `cesna172.type = "r";`
“error: assignment to expression with array type”, I don’t understand it, I defined a array in my structure. The first and second method use the same syntax.

here we go:

``````cesna172.type[2] = 'r';
``````
