converting an array of integers to string

Question

If I have an array that looks like

int digits[size] = {0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 1, 2, 3, 0, 4}

I want to remove the leading zeros and to d

You can use a string stream to convert from any type to string:

#include  //<-- ALLOWS USE OF std::stringstream 
const int size = 15;

int digits[size] = {0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 1, 2, 3, 0, 4};

std::stringstream ss;  //<-- DECLARE STREAM

int k;
for (k = 0; k < size; ++k)
        if (digits[k] != 0)
                break; //FIND FIRST NON-0 INDEX

for (int i = k; i < size; ++i)
                ss << digits[i]; //ADD TO THE STREAM s

std::cout<< ss.str() << std::endl; //PRINT STREAM
