这个转换在我们日常的编码中还是很有机会遇到的,这里贴出来和大家分享探讨. void pu_hex_to_binary(std::string strHex, std::string &strBinaryResult) { for ( int i = 0; i < strHex.size(); ++ i ) { char chTemp = strHex[i]; int chHexValue; if ( 'F' >= chTemp && chTemp >= 'A' )…

How to convert a byte to its binary string representation For example, the bits in a byte B are 10000010, how can I assign the bits to the string strliterally, that is, str = "10000010". ; String s1 = String.format('); System. ; String s2 = Stri…

C++ int与string的转化 int本身也要用一串字符表示,前后没有双引号,告诉编译器把它当作一个数解释.缺省 情况下,是当成10进制(dec)来解释,如果想用8进制,16进制,怎么办?加上前缀,告诉编译器按照不同进制去解释.8进制(oct)---前缀加 0,16进制(hex)---前缀加0x或者0X. string前后加上双引号,告诉编译器把它当成一串字符来解释. 注意:对于字符,需要区分字符和字符表示的数值.比如:char a = 8:char b = '8',a表示第8个字符,b表示…
