when an array is a pointer...why the confusion?...an "array name in an expression" is a pointer...why C treats array subscripts ...

Why the Confusion? Why do people wrongly think that arrays and pointers are completely interchangeable? Because they read the st ...

which clearly demonstrate the interchangeability of pointers and arrays. It's too easy to overlook that this only happens in the ...

The executive summary of this is roughly that arrays and pointers are like limericks and haikus: they are related art forms, but ...

What "Multidimensional" Means in Different Languages The Ada standard explicitly says arrays of arrays and multidimensional arra ...

Arrays in C Are One-Dimensional Whenever you see "array" in C, think "vector," that is, a one-dimensional array of something, po ...

The dimensions of the array that the pointer points to make a big difference. Using the declarations in the example above, r++; ...

The most common use of multidimensional arrays in C is to store several strings of characters. Some people point out that rightm ...
