How to check if all values in bool array are true?

Question

In C , what is the best and simplest way to check if all values in a bool table are true? I tried something like this but it doesn't work

for(i = 0; i < value; i++){
            if(bool_table[i] == 0)
                table_true = 0;
            else
                table_true = 1;
    }

The problem with this code is that sometimes if the first value is true then it will set table_true = 1

Answer 1

Something like this should do the trick:

table_true = 1;
for(i = 0; i < value; i++)
        if (!bool_table[i]) {
            table_true = 0;
            break;
        }

Answer 2

If the following loop goes through the entire array without finding a false entry, then at the end of the loop i will equal value

for(i = 0; i < value; i++)
    if ( !bool_table[i] )
        break;

table_true = (i == value);

Answer 3

I'm not sure how one evaluates "best" or "simplest." Does "best" mean fastest? Or least lines of code? And simplest, is that most simple for a beginner? Or for a group of developers that eat and sleep C and use pointers regularly?

Here's my somewhat unconventional approach:

bool *each = bool_table; // pointer to first element
bool *end = each + value; // stop condition
while (*each && each != end) {
    each++;
}
return each != end;
