That's easy enough to do: int val, min, max, avg; max = avg = 0; min = -1 ^ (1 << sizeof(int) * 8 - 1); for (int i = 0; i < 1000; i++) { //load your random number into val here if (val < min) { min = val; } if (val > max) { max = val; } avg += val; }
Note: On the first min = line, we're shoving in the largest value possible into min. That way, the first random number is guaranteed to be smaller than min.

Summary: im at a bit of a loss here. I never had to work with strings, so forgive me if it is trivial: i want to have an array of strings in C++, for example: string array[10]; array[0] = "I dont"; array[1] =...
Summary: What you're talking about is using pointers and allocating memory. You need to be careful here because this is how memory leaks occur: #include "stdlib.h" /* your array: */ char *array; /* sizing you...
