Debug short c++ code

Please can you fix the bug where i'm getting for some values of orderReverse -1 original value from order ? //main int order[4] = { 0 }; while (nDataLen >= 2 * 4) { func3(order, readFile); unsigned int previous = 0; unsigned int w = 1; for (int i = 0; i < 4; i++) { previous += w * (order[i]); w *= 256; } } char bitStringr[33] = {'0'}; Get_string32_from_SIZE4_VALUE(bitStringr, previous); int orderReverse[56]; orderReverse[0] = Get_CHAR_ARRAY_SIZE4_FROM_VALUE(bitStringr); int ic = 0; char bitStringr1[33] = {'0'}; for (int i = 8; i < 16; i++ ) { bitStringr1[ic] = bitStringr[i]; ic++; } orderReverse[1] = Get_CHAR_ARRAY_SIZE4_FROM_VALUE(bitStringr1); ic = 0; for (int i = 16; i < 24; i++) { bitStringr1[ic] = bitStringr[i]; ic++; } orderReverse[2] = Get_CHAR_ARRAY_SIZE4_FROM_VALUE(bitStringr1); ic = 0; for (int i = 24; i < 32; i++) { bitStringr1[ic] = bitStringr[i]; ic++; } orderReverse[3] = Get_CHAR_ARRAY_SIZE4_FROM_VALUE(bitStringr1); //Functions void Get_string32_from_SIZE4_VALUE(char* sz_output, unsigned int val) { sz_output[0] = 0; unsigned int v = 1; unsigned int n = 0; for (int i = 0; i < 32; i++) { sz_output[n++] = (val & v) ? '1' : '0'; v <<= 1; } sz_output[n] = 0; } char Get_CHAR_ARRAY_SIZE4_FROM_VALUE(char* sz_input) { unsigned short v = 1; unsigned short n = 0; for (int i = 0; i < 32; i++) { n += (sz_input[i] == '1') ? v : 0; v <<= 1; } return n; } void func3(int* dst_Array, FILE* src_InputFile) { char buf[8];///////////////////////////// fread(buf, 1, 8, src_InputFile); for (int i = 0; i < 4; i++) { dst_Array[i] = buf[i]; } }
