Check if a value exists in an array in Cython

Question

I want to know how to check if a value or a object exists in an array, like in python:

a = [1,2,3,4,5]
b = 4
if b in a:
    print(\"True!\")
else:
    print(         


        

Answer 1

You pretty much have to iterate through the array and check each element.

#include 

bool isvalueinarray(int val, int *arr, int size){
    int i;
    for (i=0; i < size; i++) {
        if (arr[i] == val)
            return true;
    }
    return false;
}
