I made the code below, however I have a problem in the test code like \'a.out: ex2.cpp:20: int main(): Assertion `countOccurrences(a,1,6) == 2\' failed. Aborted\'. what is the problem of my test code? # include <iostream> #include <cassert> using namespace std; int countOccurrences(int a[], int len, int k){ int occurrences = 0; for (int i = 0; i < len; ++i){ if (a[i] == k) ++occurrences; } return occurrences; } int main(){ int a[] = {1, 1, 5, 7, -11, 23}; assert(countOccurrences(a,1,6) == 2); assert(countOccurrences(a,2,6) == 0); assert(countOccurrences(a,5,6) == 1); assert(countOccurrences(a,7,6) == 1); assert(countOccurrences(a,-11,6) == 1); assert(countOccurrences(a,23,6) == 1); } I made this Solution Hi, I have updated your code. There is an issue with parameter mapping from calling function to called function. Highlighted the code changes. it is working fine now. #include <iostream> #include <cassert> using namespace std; //int countOccurrences(int a[], int len, int k){ int countOccurrences(int a[], int k, int len ){ int occurrences = 0; for (int i = 0; i < len; ++i){ if (a[i] == k) ++occurrences; } return occurrences; } int main(){ int a[] = {1, 1, 5, 7, -11, 23}; assert(countOccurrences(a,1,6) == 2); assert(countOccurrences(a,2,6) == 0); assert(countOccurrences(a,5,6) == 1); assert(countOccurrences(a,7,6) == 1); assert(countOccurrences(a,-11,6) == 1); assert(countOccurrences(a,23,6) == 1); } .

1. I made the code below, however I have a problem in the test code like 'a.out: ex2.cpp:20: int
main(): Assertion
`countOccurrences(a,1,6) == 2' failed. Aborted'.
what is the problem of my test code?
# include <iostream>
#include <cassert>
using namespace std;
int countOccurrences(int a[], int len, int k){
int occurrences = 0;
for (int i = 0; i < len; ++i){
if (a[i] == k) ++occurrences;
}
return occurrences;
}
int main(){
int a[] = {1, 1, 5, 7, -11, 23};
assert(countOccurrences(a,1,6) == 2);
assert(countOccurrences(a,2,6) == 0);
assert(countOccurrences(a,5,6) == 1);
assert(countOccurrences(a,7,6) == 1);
assert(countOccurrences(a,-11,6) == 1);
assert(countOccurrences(a,23,6) == 1);
}
I made this

2. Solution
Hi,
I have updated your code. There is an issue with parameter mapping from calling function to
called function. Highlighted the code changes. it is working fine now.
#include <iostream>
#include <cassert>
using namespace std;
//int countOccurrences(int a[], int len, int k){
int countOccurrences(int a[], int k, int len ){
int occurrences = 0;
for (int i = 0; i < len; ++i){
if (a[i] == k) ++occurrences;
}
return occurrences;
}
int main(){
int a[] = {1, 1, 5, 7, -11, 23};
assert(countOccurrences(a,1,6) == 2);
assert(countOccurrences(a,2,6) == 0);
assert(countOccurrences(a,5,6) == 1);
assert(countOccurrences(a,7,6) == 1);
assert(countOccurrences(a,-11,6) == 1);
assert(countOccurrences(a,23,6) == 1);
}
