In network programming, the special characters contained in the URL parameter need to be replaced with "%20" by the two-bit hexadecimal method of the ASCII code, which is converted to a character that the server can recognize, such as a space ASCII code of 32, or 16 binary 0x20.Title: Implement a function that replaces each space in the incoming char* string with "%20", such as "We are happy.", then output "we%20are%20happy."The solution idea of time complexity is O (n):First, the string is trav

Implement a function that replaces a space in a string with "%20". For example, when the string is we are Happy. The string after substitution is we%20are%20happy.Note that the time complexity is O (n), which is replaced by a backward forward.

PHP Str_replace ()Mixed Str_replace (mixed $search, mixed $replace, mixed \ (subject [, int \)count])The function returns a string or an array. The string or array is the result of replacing all search in subject with replace.If there are no special substitution requirements (such as regular expressions), you should use this function to replace ereg_replace () and Preg_replace ().$arr = Array ("str_1", "str_2", "str_3");echo str_replace ("'", "'", $ar

this basis. The EXEC function family provides six ways to start another program in the process . The function of the EXEC function family is to find the executable file based on the specified file name or directory name, and use it to replace the contents of the calling process, in other words , execute an executable file inside the calling process.When a process calls an EXEC function, the process is completely replaced by the new program, and the new program executes from its main function. B

function, the process is completely replaced by the new program, and the new program executes from its main function. Because calling exec does not create a new process, the process ID of the front and back (and of course the parent process number, the process group number, the current working directory ...). ) has not changed. exec simply replaces the body, data, heap, and stack (process substitution) of the current process with another new program
