First of all, the file operation and string and character in-depth processing (that is, what puts (), GetChar () or something) is my deep understanding of C + + the last two mountains. Today, the redirect file operation is resolved

Today, my classmates asked me if there is any simple way to find out the sum of two numbers in C + +, then there is a way to title.The return value of LOG10 (100) is the return value of 2,log (999) is more, but if you position the return value int,
