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';
