c# - Why is that var can only be declared and initialized in a single statement? -


why var can declared , initialized in single statement in c#?

i mean why cannot use:

var x;  x = 100;

since implicit typed local variable "var" , compiler takes type right of variable assignment operator, why matter should declared , initialized in single statement?

because statement declares variable needs imply type in order compiler know var. sure, person own intuition can logically step through code , determine type will be. compiler isn't complex human intuition. needs type defined in statement in order compile statement logically complete action.

every statement needs individually complete , compilable.
