Good day.

There are two files: main.c

#include <stdio.h> #include <stdlib.h> int main(void) { FillingABC(a, b, c); FillingABC(); return 0; }

And Functions.c

 #include <stdio.h> #include <stdlib.h> #include <time.h> int n; int a[20], b[20], c[20]; // Π’ Π·Π°Π΄Π°Π½ΠΈΠΈ сказано, Ρ‡Ρ‚ΠΎ ΠΎΠ½ΠΈ Π½Π΅ большС 20 int x[20], y[20]; // Π—Π°ΠΎΠ΄Π½ΠΎ Π²Ρ‹Π΄Π΅Π»ΠΈΠΌ ΠΈ для x, y void FillingABC () { srand(time(NULL)); for (int i = 0; i < 20; i++ ) { //ЗаполняСм массив Π° случайными числами ΠΎΡ‚ 1 Π΄ΠΎ 50 int number = 0 + rand() %50; a[i] = number; printf("%d ", a[i]); //Π’Ρ‹Π²ΠΎΠ΄ΠΈΠΌ массив Π° } printf("\n"); for (int i = 0; i < 20; i++ ) { //ЗаполняСм массив b случайными числами ΠΎΡ‚ 1 Π΄ΠΎ 50 int number = 0 + rand() %50; b[i] = number; printf("%d ", b[i]); //Π’Ρ‹Π²ΠΎΠ΄ΠΈΠΌ массив b } printf("\n"); for (int i = 0; i < 20; i++ ) { //ЗаполняСм массив c случайными числами ΠΎΡ‚ 1 Π΄ΠΎ 50 int number = 0 + rand() %50; c[i] = number; printf("%d ", c[i]); //Π’Ρ‹Π²ΠΎΠ΄ΠΈΠΌ массив c } printf("\n"); }

Actually, I want to get rid of two extra for-s, and in main.c simply call the FillingABC function for arrays a, b, and c. How to do it right?

    You just need to pass an array to the function as an argument. And create them in main.c. For each array, call the function separately. I.e:

     void Fill (int* ar, int n) { for (int i = 0; i < n; i++ ) { int number = rand() % 50; ar[i] = number; printf("%d ", ar[i]); } printf("\n"); } int main(void) { srand(time(NULL)); int n = 20; int a[n], b[n], c[n]; Fill(a, n); Fill(b, n); Fill(c, n); return 0; }

    In general, in order to make the code shorter, understandable, and universal, variables, numbers in arguments and constants should be placed.
