How to check if an array is strictly increasing in C

Answer 1

#include <stdio.h>
#include <stdbool.h>

bool strictly_increasing(int arr[], int size) {
    for (int i = 0; i < size - 1; i++) {
        if (!(arr[i] < arr[i + 1])) {
            return false;
        }
    }
    
    return true;
}

int main() {
    int arr[] = {1, 3, 4, 6, 8, 9, 11, 17, 18, 37};
    int size = sizeof(arr) / sizeof(arr[0]);
    
    printf("%s\n", strictly_increasing(arr, size) ? "true" : "false");
    
    return 0;
}
