What is the difference Between those types of initializing An array called "IntegerArray" With 5 element : Code: int IntegerArray[5] = {0}; int IntegerArray[5] = {0,0,0,0,0}; int IntegerArray[5] = {10,20,30,40,50}; int IntegerArray[] = {10,20,30,40,50}; Please i need an obvious explanation for each line as i am confused..... Thanks for reading...............
Code: int IntegerArray[5] = {0}; Declares array of integers with each initialized to 0. Basically short form of second one. Code: int IntegerArray[5] = {0,0,0,0,0}; Declares array of integers with each initialized to 0. Code: int IntegerArray[5] = {10,20,30,40,50}; Declares array of integers with each initialized to respective values. Code: int IntegerArray[] = {10,20,30,40,50}; Declares array of integers with each initialized to respective values. This is again same as above and one more way to write it.
By all means the explanation of shabbir was excellent, indeed. Just a little complementation from me: when you write int a[n] = {a[1], a[2] ..., a[t]} then, if n is greater than t, then the remaining values are set to 0. t is greater than n, this is a compile error. if you don't specify n, then n = t; sorry for a bit dry explanation, but I'm sure it won't cause trouble
