Here you defined char array text which type is character type . And you mentioned array size 20 it means your array can store 20 characters. For example char text[5]= "Helloworld"; Here i gave array size 5 and my total chars are 10 so it will give you errors so it represent your size . If u dont want to mention size the u can write like this char text[ ]= "Helloworld"; Here in bracket don't mention size your array will take size automatically and it will run without error.

when defining that variable, you have to specify size of character array. In your case it is 20.

Supporting ♨️TEJAS MK-82♨️ 's answer, Technically yes, you declared an array of chars of size 20, it has the index of [0] to [19] but I suggest you assign a value to it for maximum of 19 characters (until index [18], because index [19] will be used as a string terminator, the '\0' character). The point is, it is correct to say it CAN store 20 characters, but you SHOULD store 19.
