we can write code for all the inbuilt functions with out using that inbuilt function
for example
strlen(stringname) gives length of the string
but without using...

should the output give
5=1+4
also ??
if not
how did u specify that only those outputs have to be shown??

can you be a littlie bit more specific
couldnt understand what u told

this will work

i am using a turbo c2 compiler

hi every one

i want to draw a circle using graphics


#include<stdio.h>
#inlcude<graphics.h>
{
circle(20,20,10);
getch();

#include<stdio.h>
main()
{
int n,i,f=0;
printf("enter any number");
scanf("&#37;d",&n);
for(i=2;i<n;i++)
{
if(n%i==0)
f=1;

in c we need not mention return type
directly we can use main();


but in c++ we have to mention return type
ie void main();
or int main();
etc why is this so??

in c if we use main();
we donot get any error
but in c++ we have to mention the return type
can any one tell me why is this??

hey can u tell me why fflush is wrong??
still it clears your problem??

can you give an example
or be a little bit clearer

#include <stdio.h>
#include <string.h>

int main(void)
{
char name[20];
float weight;
float height;

printf("Enter your name:");

#include <stdio.h>

int main(int argc, char** argv)
{
char c;
int d;
printf("Enter a no:\n");
scanf("&#37;d",&d);
printf("Enter a character\n");
fflush(stdin);
