WebJul 15, 2024 · The code works correctly. The function sizeof() returns the number of bytes in a variable, not the number of elements. Your array is of type int, which consists of 2 bytes each.So in sum you get 6 bytes for the whole array. What you want to do (calculating the number of elements in the array) is to divide the number of bytes in the array by the … WebApr 13, 2024 · int转byte的实现方法; 一、byte转int的实现方法. 在Golang中,byte是一种基本的数据类型,表示的是8位无符号的整数,范围为0~255。而int则表示有符号整数类型, …

The buffer doesn't receive any ASCII character and I believe the toInt () function won't work if it's not an ASCII character. The int size should be 37 (0x25), but - as I have said - it's 0.

The hex number 0x80 is interpreted as a negative integer, because QByteArray uses (signed) char to store bytes internally. Casting -128 to a quint32 yields the two's complement. The fix is to cast to quint8. auto b = static_cast(bytes[count - 1 - i]); delete a remote branch github
