Combining chars into a char array

Projects Programming
1

Hello,
I'm trying to combine some char values into a single char array. I can't seem to get this right. This is what it looks like right now.

char keyPin0 = '1';
char keyPin1 = '2';
char keyPin2 = '3';
char keyPin3 = '4';
char keyPin4 = '5';

char keyNums[5];

keyNums = keyPin0 + keyPin1 + keyPin2 + keyPin3 + keyPin4;

Also, when I try to print onto my lcd screen it just prints the combined ascii values added together and only prints the one character.

lcd.print(keyPin0 + keyPin1 + keyPin2 + keyPin3 + keyPin4);

You can just use one array for both. Then your data is already there.

char keyNums[ 5 ] = {
  '1',
  '2',
  '3',
  '4',
  '5',
};

void setup() {
  
  char c = keyNums[ 0 ];

  //Or 
  lcd.write(keyNums, 5);
}

void loop() {}

EDIT: I removed the enum to simplify it.
