Solution

The error is you aren\'t passing valid parameters to countOccurences function.

Placed the working code below

#include <iostream>
#include <cassert>
using namespace std;
int countOccurences(int a[],int len,int k)
{
    int i=0,count=0;
    for(i=0;i<len;i++)
    if(a[i]==k)
    count++;
    return count;
}
int main(){
    int a[]={1,2,3,4,3,2,1};
    int k=3;
    assert(countOccurences(a,7,k));
    return 0;
    cout<<\"All tests passed.\"<<endl;
}
