Question from a beginner
Downloaded Bloodshed Dev-C++ and put a learningbook next to it about programming in C.
Entered the following code :
main( )
{
printf("hello, world");
}
Simple first program, but get after compile and run the error :
implicit declaration of function `int printf(...)'
Nice thing for a starter huh ?
What's wrong ?
Second question, what's the function in C/C++ for the Pascalfunction Readln ?
Would be nice to see the little Dos screen stay up to see what I've have have done.
add #include <stdio.h>
before your code and it should work
stdio.h contains the defn of the printf fn
jv
Thx for awesome quick reply, Rasrajva
It worked, but how to have the pop-up Dos screen to stay up to actually see the line " hello, world" e.g to see my compiled output ??
you need to call a fn that waits for an enter or something at the end of your program
i normally do it this way
#include <stdio.h>
#include <conio.h> /*for getch()*/
int main(void)
{
printf("Hello World!");
getch();
return 0;
}
jv
worked perfect, thx again
What are btw your idea of learning programming in C\C++ ?
First C and then C++, or better start directly with C++ ?
any way would do really
they make look similar
but are essentially different languages
c++ is a superset of c but to use it effectively it should not be used like c is used
so whichever way you go no trouble
only i blieve evryone should know c
and i learnt em in that order so go for c first and then c++ if youve got the time
jv
Hello.
To learn C++, you are learning C at the same time, except with different i/o standards, and a different programming paradigm. Although, to learn OOP, is to learn Procedural Programming, except with the addition of objects, which is the basis of OOP.
So basically, it is a strange philosophical question. To learn C++, you are learning C, but also, you are learning a totally different language. I hope that was enlightening to you, it certainly was for me.
