/* this is my code, only thing I'm missing is counting
zeros...WHAT THE HELL am I doing WRONG?*/

#include <stdio.h>

#define ROWS 50
#define COLS 50

int count_occur(int A[], int num_elements, int value);


int main(void)
{
int A[ROWS][COLS];
int i=0, j=0;
int num_occ, value=0;

/* Initializing*/

for(i=0; i < ROWS; i++) {
for(j=0; j < COLS; j++) {
A[i][j] = 0;
A[i][j] = rand() % 2;

}
}

for(i=0; i < ROWS; i++) {
for(j=0; j < COLS; j++) {

if (i == j){
printf("%2d", A[i][j]);
}
}



}

for(value=0; value<1; value++)
{

num_occ = count_occur(A, 50, value);

if (value = 1){

printf("\n\nThe value %d was found %d times.\n", value,
num_occ);
}

else if (value = 0){

printf("\n\nThe value %d was found %d times.\n", value,
num_occ);
}


}

}

int count_occur(int A[], int num_elements, int value)
/* checks array a for number of occurrances of value */
{
int i, count=0;
for (i=0; i<num_elements; i++)
{
if (A[i] == value)
{
++count; /* it was found */
}
}
return(count);
}

Write a program to check whether the number is prime and also check if it there i n fibonacci series, then return true otherwise return false
