The entire form of conio.h is "Console Input & Output." In C programming, the console input and output function is provided by the header file conio.h. Since we learned that the conio.h file has console input/output functions, the GCC compiler does not support it. Thus, we will talk about a few key features that are utilized to hold the screen, clean the screen, and adjust the text's backdrop , Possible Duplicates: *.h or *.hpp for your class definitions What is the difference between .cc and .cpp file suffix? I used to think that it used to be that: .h files are header files for C and C, I propose to simply include an All.h in the project that includes all the headers needed, and every other .h file calls All.h and every .c/.cpp file only includes its own header., The stdio.h is a file with ".h" extension that contains the prototypes (not definition) of standard input-output functions used in c., When dividing your code up into multiple files, what exactly should go into an .h file and what should go into a .cpp file?, Typically, a .h.in file is a header template that is filled in to become the actual header by a configure script based on the outcome of several tests for features present on the target platform..
