Date: 2010may13 Language: C/C++ Q. How can I delete an element from an array in C/C++ ? A. Here is an example of a function that can do it:

inline void DeleteArrayElement(THING a[], const int i, const int n) { memmove(&a[i], &a[i+1], (n - i - 1) * sizeof(THING)); } void ExampleUse() { THING my_things[20]; // Declare the array // ... // put some stuff into the array // ... // Delete element 5 DeleteArrayElement(a, 5, sizeof(my_things) / sizeof(my_things[0])); }

Use erase() to delete an element from an STL vector (which is a growable array).
