Problem is that , whenever you compile a new c program and compile it using gcc cprogram.c it will update the previous ./a.out file. You're looking for the file you coded with ".c" at the end. The command is: gcc thread.c -o thread -lpthread. so a.out file will always keep changes. As we know C is a compiled language so, first of all, we need a C compiler for compiling our source code. // (Windows) In CMD shell > g++ -o hello.exe hello.cpp // Compile and link source hello.cpp into executable hello.exe > hello // Execute under CMD shell // (Unixes / Mac OS X) In Bash shell $ g++ -o hello hello.cpp $ chmod a+x hello $ ./hello More GCC Compiler Options Steps to Compile and Execute C Program in Linux Using Gcc Before talking of compiling and running C program in Linux let's see why C is so popular ever since it was created. To compile C program first.c, and create an executable file called first, enter: $ gcc first.c -o first OR $ cc first.c -o first To execute program first, enter: $ ./first Output: My first C program. While compiling hello.c the gcc compiler reads the source file hello.c and translates it into an executable hello.The compilation is performed in four sequential phases by the compilation system (a collection of four programs - preprocessor, compiler, assembler, and linker).
