I would not go with c# at all, it has bigger binary sizes, is slower, it also forces oop down your throat. for cp I would just stick with c++.
Anonymous
for cp you do not want a bunch of overhead or boilerplate both of which c# brings
Mar!o
C++ is fine for CP but remember that most code written for CP is shit code

hey i am doing c language on vs code
Anonymous
my code is #include<stdio.h>
void main()
{
int r;
float a;
printf("enter the radius of circle :\n");
scanf(" %d",&r);
a=3.14*r*r;
printf("s %f s the area",&a);
}
Anonymous
why are you using a pointer to a in printf
Anonymous
the output is -1.#QNAN0 s the area
Anonymous
yes

&a should just be a
Adarsh
&a will print address of a

Can we optimize this code?
#include<iostream>
using namespace std;
#define MAX 200
void fact(int n)
{
int arr[MAX];
arr[0]=1;
int arrSize=1;
for(int x=2;x<=n;x++)
{
int carry=0;
for(int i=0;i<arrSize;i++)
{
int product = arr[i]*x+carry;
arr[i]=product%10;
carry=product/10;
}
while(carry)
{
arr[arrSize]=carry%10;
carry=carry/10;
arrSize++;
}
}
cout<<"Factorial :";
for(int i=arrSize-1;i>=0;i--)cout<<arr[i];
}
int main()
{
fact(5);
return 0;
}
Hariyana Grande
#include<stdio.h>
int main(){
int glob=20;
{
extern int glob;
printf("%d",glob);
}
printf("%d", glob);
return 0;
}
Hariyana Grande
its giving error why?
Hariyana Grande
do we need to declare ext outside main?
Anonymous
Don't use something you don't understand
Hariyana Grande
how do you learn if you dont try different things
Eturnus
#include<stdio.h>
int main(){
int glob=20;
{
extern int glob;
printf("%d",glob);
}
printf("%d", glob);
return 0;
}
#include<stdio.h>
extern int glob=0;
int main(){
glob=20;
printf("%d\n",glob);
printf("%d", glob);
return 0;
}
Hariyana Grande
these type of problems are common in multiple choice tests
Hariyana Grande
Hariyana Grande
Eturnus
yes
Hariyana Grande
#include<stdio.h>
extern int glob=0;
int main(){
glob=20;
printf("%d\n",glob);
printf("%d", glob);
return 0;
}
there are 4 options given a) 0 0 b) 0 20 c)20 0 d) linker error for the program i posted what do u think might be the answer then?
Eturnus
because glob=20;
initialized in program
Hariyana Grande
yes that i know now but what about original program
Hariyana Grande
what is the right ans there
Eturnus
your program not gonna run
Hariyana Grande
linker error
Eturnus
as extern variable not defined
Hariyana Grande
so out of 4 options linker error thanks

what is the problem in this code
Papa
the question of this problem is Write the code that fills the elements with an even index with integer 0 and the

You don't initialize array, and doesn't assign to its element values
