However, when you have a long list, counting things can be more challenging.To count objects, you typically use a counter, which is an integer variable with an initial value of zero. Then you increment the counter to reflect the number of times a given object appears in the input data ...

C cruncher.c void increment(int* numbers, unsigned int length) { for (int i = 0; i < length; i++) { numbers[i]++; } } The function expects a pointer to an array of signed integers as well as the length of the array. The second argument is necessary because C doesn’t keep...
