Compilers is what you need to know.First you type in our common language such as English,but a computer can't understand our language.So,it coverts everything we input into it into it's machine language or into binary source code.But c and c++ are like a common language for both of the human and the computer.They are called middle-level languages.So,when you input the data into c,using certain keywords and header files and other tools,it first scans the entire data for any wrong keyword input or undefined characters.If no error is observed,it compiles the whole thing into it's language.It takes place when we press Ctrl.+F9.But it gives the output as per our requirement.So,it scans,compiles and produces the output to execute.The same way,it is used to design softwares and applications at higher levels.
