  • 0
const char *sentence = "He was not in the cab at the time.";

printf("\"%s\" has %d spaces\n", sentence, (int) ^ {
    int i = 0;
     int countSpaces = 0;

    while (sentence[i] != '\0') {
        if (sentence[i] == 0x20) {
            countSpaces++;
        }
        i++;
    }    
    return countSpaces;
});

This code simply counts the white space in a string, but for some reason it says 1606416608 spaces rather than 8. I’m not exactly sure what is going wrong, so thanks for any help!

    You’re passing the actual block to printf, not the result of the block. Instead, try

    const char *sentence = "He was not in the cab at the time.";

printf("\"%s\" has %d spaces\n", sentence, (int) ^ {
    int i = 0;
    int countSpaces = 0;

    while (sentence[i] != '\0') {
        if (sentence[i] == 0x20) {
            countSpaces++;
        }
        i++;
    }    
    return countSpaces;
}()); // <-- note the extra parentheses here, indicating that you're calling the block
