The layout of a process in memory:. Text segment (body segment)--the program binaries that the program executes, the machine instruction portion of the CPU execution, a program with only one copy, and read-only to prevent the program from modifying

The first program everyone knows (I use the vs2013 here) int Main () { printf (" my first program "); return 0 ;} // Note This error occurs because of error 1 C2143: syntax error: Missing ";" (in front of "return")
