Hi everyone. Is anybody used from eigen library before? I have some problem by including it. I have installed it by
sudo apt install eigen3-dev
in linux but when I import it by #include(Eigen/Dense) I get an error. Can you please help me?

#include<stdio.h>
#include<string.h>
int main()
{
char s1[50] = "Harry";
printf("After reversing string is =%s", strrev(s1));
return 0;}
//Output: After reversing string is = yrraH
Please help me . I getting error in this code ..
Please help me in...correcting the error in code

strrev is non-standard.
Abhishek Gupta
I using Dcoder...
Abhishek Gupta
what compiler are you using and it's version?
Can you please suggest how we reverse an string in C using string functions
mito
see for alternative for strrev()

If you input 60 and 3.5 as velocity and acceleration
It is meant to give 514
But it is outputting 0

Can anyone help?

Can anyone help?
IMO do separate the scanf statements
ie. scanf(......)
scanf(......)
And actually prototype the square function instead of trying to make it a macro
ie. int square(x){
return x*x
}

What if I define it
ie. #define square(x) x*x

I don't believe that works for functions
(I stand to be corrected)
A function prototype is the way to go

Are rust and c++ same? Do they have same vendors or what?

They are not the same. iirc rust was planned to be a successor to c++ but it is not the same language.

I have searched and cant find a good answer. Any idea if c++ has a way to read charactors in letter by letter as they're typed instead of waiting for the user to press enter?

Rust design concept ais different with C++, not just because rustc is written with C++ rust is same with C++

i did it but i don't know to do it using pointers
pointer used to access array
arr[x] is same as *(arr + x)

i did this
now how can i do it using pointers

Array are pointer
also The result must be returned and printed in the main function.

Velocity is float but the type is int

hi , got any apps that can use to check the coding?
Prateek
Write a program that reads in a number m and prints a '*' on m consecutive lines, followed by m+1 '*'s on a single line. The result should look like the letter L made out of stars. You can go to a new line in the output using cout << endl; .

Just use loops
klimi
you cannot reallocate something you haven't allocated
klimi
exactly, it is only for the allocation on the heap
klimi
but in this case ages have been allocated on stack

1- your bracket are currently not well balanced
2- Why did you write something like 'q.name;' (after the variable declaration) for ??

you must allocate with malloc or calloc first then u can use realloc to adjusting it.

The program will run in any platform as long as the code following standard

Static memory cannot be reallocated?
