the output'MessageBox (buf );Fclose (pFile );Garbled characters appear because '/0' is not found in time during the output file. Change strlen of the file to sizeof.When a file read/write function needs to read/write, it carries '/0'. It is similar to functions such as printf and strlen that end with'/0' as the function.Garbled code can also be usedFILE * pFile = fopen ("c: // 1.txt"," r ");Char buf [100];Fseek (pFile, 0, SEEK_END );Long len = ftell (pFile );Rewind (pFile );Fread (buf, 1, len,

problems. Please refer to the following Program :# I nclude Int iarray [2] = {99,10 };Void main (){Ofstream OS ("test. dat ");OS. Write (char *) iarray, sizeof (iarray ));}When the execution program outputs data to the file, 10 is automatically converted to 13. However, the conversion here is obviously not what we need. To solve this problem, we need to use the binary mode output. When binary mode is used for output, the characters in the output are not converted. The following methods can be u

also be noted that the header files used by scanf and printf should be stdio.h instead of iostream.I do not know this pair of functions to live today, before encountering Cin Tle always foolishly changed to scanf, and even believe that C + + in the IO aspect of inefficient nonsense, but this is only C + + to be compatible with C and take the conservative measures.TieThe tie is a function that binds two stream, and the null argument returns the current output stream pointer. #include #in

Inherited: Inheritance is a relatively central concept in object-oriented. Other Orthodox object-oriented languages can be implemented in two ways Commitment: One is an interface implementation, and the other is inheritance. While ECMAScript only supports inheritance, it does not support interface implementations, and realThe way it is inherited relies on the prototype chain to complete.function Box () {//box constructionThis.name= ' Lee ';}function Desk
