Count the number of times a number appears in an array

Question

I\'m working on a small program that counts the number of times an integer appears in an array. I managed to do this but there is one thing I can\'t overcome.

My cod

Answer 1

#include 
#include 
#include 

int count_occur(int a[], int num_elements, int value, bool selected[]);
void print_array(int a[], int num_elements);

int main(void){
    int a[] = {2, 5, 0, 5, 5, 66, 3, 78, -4, -56, 2, 66, -4, -4, 2, 0, 66, 17, 17, -4};
    int size = sizeof(a)/sizeof(*a);
    bool ba[size];
    memset(ba, 0, sizeof ba);
    int num_occ, i;

    printf("\nArray:\n");
    print_array(a, size);

    for (i = 0; i

Little improvement

int count_occur(int a[], int num_elements, int index, bool selected[]);

num_occ = count_occur(a, 20, i, ba);

int count_occur(int a[], int num_elements, int index, bool ba[]){
    int i, count = 0;
    for (i = index; i
