Question

double sqrtIt(double x, double low_guess, double high_guess) {
    int n = 10;
    int num = 0;
    while ( n > 0.000000000000001){
        n = n / 10;
        while (num < x && low_guess <= (low_guess * 10)){
            low_guess = low_guess + n;
            num = low_guess * low_guess; 
            }
    }
    return low_guess;
}

I’ve tried to use the code above to find the square root of a number. the function works fine most of the time, but when the number is 2, I get the “There is no source code available for the current location. Show disassembly” error from line num = low_guess * low_guess; I don’t know what did wrong, and what does show disassembly do? Thanks

Answer 1

The “no source code available” message may indicate that you are not compiling in debug mode, so your IDE can’t do a source-level debug. I think there’s probably some confusion here, brought on by trying to deal with an IDE for the first time…

As others have said, you should probably declare n and num to be double, not int.

Probably, once you become more familiar with your development environment (as well as the language), some of these things will sort themselves out.
