WebbWhat is the size of an int array in C? To determine the size of your array in bytes, you can use the sizeof operator: int a[17]; size_t n = sizeof(a); On my computer, ints are 4 bytes long, so n is 68. To determine the number of elements in the array, we can divide the total size of the array by the size of the array element. WebbThe destination array can hold 5 values, so it has enough room to hold the 5 values that should be copied. However, because the source array only has 3 values, only the 3 values should be copied from the source array into the destination array.

The time complexity of the above code is O (N) and the space complexity of the above code is O (1). WebbThere is no fixed limit to the size of an array in C. The size of any single object, including of any array object, is limited by SIZE_MAX, the maximum value of type size_t, which is the result of the sizeof operator. (It's not entirely clear whether the C standard permits objects larger than SIZE_MAX bytes, but in practice such objects are not supported; see footnote.)
