greetings everyone!!!
its a fact that on xcode one don't have conio.h file instead curses.h can be used for using function like getch(). i did the same but my output is totally different
here is the program#include <stdio.h>
#include <ctype.h>
#include<curses.h>
int main()
{
char ch;
do{
ch=getch();
if(islower(ch))
ch=toupper(ch);
else
ch=tolower(ch);
putchar(ch);
}while(ch!='.');
return 0;
}
it is suppose to convert uppercase letter to lowercase and vice-versa.
if i use getchar it works fine but on using getch() output is infinite loop.
can anyone tell why this infinite loop is coming
A conio.h file isn't a library, it's a header file. If there isn't an implementation in some other file or files that comes with the header file, you don't have the whole thing. At most, a header file declares functions and variables, which will then need to be linked in from a conio library. C for Engineers #includeconio.h Is a header file used in C programming and contains functions for console input/output. Some of the most commonly.
You need to install following packages on Debian and Ubuntu Linux:
build-essential package – Installs the following collection to compile c/c++ program on a Ubuntu Linux including:Advertisements
- libc6-dev – C standard library.
- gcc – C compiler.
- g++ – C++ compiler.
- make – GNU make utility to maintain groups of programs.
- dpkg-dev – Debian package development tools.
Basically, build-essential package contains an informational list of packages which are considered essential for building Ubuntu packages including gcc compiler, make and other required tools. This package also depends on the packages on that list, to make it easy to have the build-essential packages installed. In this tutorial, you will learn about installing the GNU C compiler and GNU C++ compiler on a Ubuntu Linux.
Installing compilers using apt command
Open the terminal app and type the following apt command/apt-get command:$ sudo apt update
$ sudo apt upgrade
$ sudo apt install build-essential
OR$ sudo apt-get update
$ sudo apt-get upgrade
$ sudo apt-get install build-essential
Sample outputs:
Verify installation
Type the following commands:$ whereis gcc make
$ gcc --version
$ make -v
Installing the dev man pages on a Ubuntu Linux
Type the following command:$ sudo apt-get install manpages-dev man-db manpages-posix-dev
To view library calls (functions within program libraries), enter:$ man 3 scanf
$ man 2 execve
$ man 2 fork
You can write a small program to test GNU c/c++ compiler:$ vi test.cpp
Append the following code:
Save and close the program. You can compile it as follows:$ make test
OR$ g++ test.cpp -o test
You should get an executable named test in the current directory:$ ls -l test
Sample outputs:
Just run it:$ ./test
Installing the X11 development compilers
Type the following command:$ sudo apt install libx11-dev
- Ubuntu Linux Install GNU GCC Compiler and Development Environment
