1. BCD and Hexadecimal Conversion The test code is as follows: #include <stdio.h> #include <string.h> // Convert BCD to hexadecimal unsigned char bcd_to_hex(unsigned char bcd) { return ((bcd >> 4) * 10) + (bcd & 0x0F); } // Convert hexadecimal to BCD unsigned char hex_to_bcd(unsigned char hex) { return ((hex / 10) << 4) | … Read more
The pattern of the pyramid is actually an isosceles triangle. We take the number of lines displayed in the program as the height, using n to represent the number of lines, with the top layer as the first layer, incrementing downwards to the second layer, third layer, fourth layer, and so on, until the i-th … Read more

Day 57: Compatibility of Carriage Return and Line Feed in C Language The previous lecture detailed asynchronous traps in signal handling, emphasizing that signal handling functions should only perform minimal tasks (such as setting flags), and it is strictly prohibited to call non-asynchronous safe functions. It also pointed out the complexity of signal dispatch in … Read more
