What is the type of the variable b in the following declaration? #define FLOATPTR float* FLOATPTR a,b; a) float b) float pointer c) int d) int pointer

B) float pointer
jbode

B is a plain float.
FLOATPTR a,b; expands to float* a,b;, which is *parsed* as float (*a),b;. The * is bound to the declarator, not the type specifier, so only a is declared as a pointer to float. -

What will be the code for>?
Write a program that prompts the user to enter an integer from 1 to 15 and displays
a pyramid . For example if the input integer is 6 ,the output is shown below :
1
2 1 2
3 2 1 2 3
4 3 2 1 2 3 4
5 4 3 2 1 2 3 4 5
6 5 4 3 2 1 2 3 4 5 6Enter key carriage return or linefeed?
When we press enter to end the program and press Alt+F5 to see the output again, we see that the getche() function places the cursor at the beginning of the line. So, does the enter key specify carriage return in this case. But while entering output, it works as a newline character... Please explain the difference in both the contexts.
A program in C using Void Pointer
c#include
#include
int main()
{
int a=10;
void *p;
p=&a;
clrscr();
printf("%u",*p);
getch();
return;
}
I know that this program is wrong as error is shown on compiling it.
Anyone please provide a simple program using Void pointer in C.
Thanks in advance :)Ashok Kumar Orupalli

You have to typecast void pointer to int as *(int*)p;
Code- #include<stdio.h>
- #include<conio.h>
- "%u"

Your error is on line 9, where youve attempted to dereference a pointer to void (the expression *p). You can only dereference typed pointers. The solution you are probably looking for would be to repl...
Getch function declaration
Can you please explain the declaration of getch() function that is "int getch(void)"?
I have the doubt that if its return type is int, why is the character typed from the keyboard is displayed as it is? It should be displayed in its ASCII value. Also, what does void as parameter in this function stand for???

In C, all the character-oriented functions (getc, fgetc, getchar, etc.) return int instead of char, mainly to support an out-of-band value for EOF (an integer expression with a negative value).
The "void" in the parameter list indicates that the function takes no parameters.Print colors with printf
Is it possible to print colors with printf statements ?

Include conio.h header file and textcolor(int value) function and dont forget to use cprintf statement : ex:
now hello world will be displayed in yellow colorCode- span style="color: #ff0000;">"hell world");

Not directly. The printf function simply sends formatted text to the output stream. However, with some terminals, you can send control codes as part of the formatted text, and these control codes ca...

How to return multiple values in C language function?
Arpita Mishra

Multiple values can be returned from a function by using call by address i.e. pointers intelligently.
jbode
- Jan 3rd, 2012
Strictly speaking, a C function can only *return* a single value; you cant write something like "a,b,c=f();". However, you can write to multiple function parameters in addition to returning a value (...
