Martin Richards, creator of the BCPL language (a precursor of C), designed arrays initiating at 0 as the natural position to start accessing the array contents in the language, since the value of a pointer p used as an address accesses the position p+0 in memory.

Primary Why in C language is it the case that a[5] == 5[a]? The C standard defines the Array Subscript Operator [] as follows: a[b] == *(a + b) Therefore a[5] will evaluate to: *(a + 5) and 5[a] will evaluate to: *(5 + a) and from elementary math we know those are equal. This is the direct artifact of arrays behaving as pointers, "...
Primary Why isn't sizeof for a struct equal to the sum of sizeof of each member? This is because of padding added to satisfy alignment constraints. Data structure alignment impacts both performance and correctness of programs. Here's an example using typical settings for an x86 processor (all used 32 and 64 bit modes): struct X { short s; /* 2 bytes */ /* 2 padding bytes */ int i;...
Primary Why is one loop so much slower than two loops? Suppose a1, b1, c1, and d1 point to heap memory and code has the following loop. const int n=100000; for(int j=0;j<n;j++){ a1[j] += b1[j]; c1[j] += d1[j]; } This loop is executed 10,000 times via another outer for loop. To speed...
