IEEE754 the representation of floating-point numbers. The expression range of float type data in C language is -3.4*10^38~+3.4*10^38. Double is -1.7*10^-308~1.7*10^308,long double for -1.2*10^-4932~1.2*10^4932. Type Number of bits

Parsing of. h and. c files in C language (wonderful)In fact, to understand the difference between a C file and a header file (i.e.. h), it is necessary to understand the compiler's work process, in general the compiler will do the following

minimum Spanning TreeSelecting the n-1 edge in a connected graph with n vertices, constituting a minimal connected sub-graph, and minimizing the sum of the weights of the n-1 bars in the connected sub-graph, it is called the smallest spanning tree

New Keywords Auto The first effect of introducing auto in C++11 is for automatic type deduction. Automatic type deduction for auto, used to infer the data type of a variable from an initialization expression. The automatic type deduction of auto
