c - Setting an array to one value

Question

Is there an easier way in C to set an array to one value than using a for loop and going setting each value one by one?

Answer 1

If you're setting the array to all 0's, or if the array is an array of bytes, you can use memset

// Set myArray to all 0's
memset(myArray, 0, numberOfElementsInMyArray * sizeof(myArray[0]));

If you need to set it to something other than 0 in units larger than a byte (e.g. set an array of ints to 1's), then there is no standard function to do that -- you'll have to write your own for loop for that.
