Write a program that takes a number from the user and displays its most significant digit.

Please answer these two questions.

Most significant digit?
#inclide <stdio.h>
#include <stdlib.h>
int main(int argc, char *argv[]) {
int num = (argc > 1) ? atoi(argv[1]) : 0;
char str[128];
sprintf(str, "%d", abs(num));
printf("%c\n", str[0]);
return 0;
}
Of course this is not proper C++, it should be done in a C++ way.

I have tried Google but came up empty and it point to other languages
I know assert()
Anyone know what is assert_op()? Is this in-built function in C?

i don't know the problem with this code.It works perfectly when first polynomial has upto 2 terms.But when it has 3 terms , the programs terminates without asking the second polynomial.
Don Peter Joseph
Enter the first polynomial
Enter the terms in increasing order of exponents
Enter the coefficient and exponent of the term 1:2 3
Do you want to add more terms?1-YES 0-NO
1
Enter the coefficient and exponent of the term 2:4 7
Do you want to add more terms?1-YES 0-NO
0
The entered polynomial is :2(x^3)+4(x^7)
Enter the second polynomial
Enter the terms in increasing order of exponents
Enter the coefficient and exponent of the term 1:4 2
Do you want to add more terms?1-YES 0-NO
0
The entered polynomial is:4(x^2)

Does anyone here have a web programming group? or DB group..?

It is normal that calling a C++20 coroutine (from a coroutine) leads to dandling references?
ex:
```
cppcoro::task<size_t> foo(const std::string& str)
{ co_return str.size(); }
cppcoro::task<> bar() { co_await foo("Hello World"); } // crash
```

Structure is return sizeof() sum all of elements inside him?

Example :
struct b{
Int a;
Int b;
}
In this example int = 4B;
sizeof(b) = 8byte?

Try exercises or projects where you need to use nested loops, and if you face no problem in using nested loops. Then, it means it is enough for you.

Not exactly, sizeof(type) gives the memory blocksize of a type obj[1] and includes any alignment padding added by compilier. Use type *array = malloc(len * sizeof(type)); for dynamic arrays.
Jaaa
Which clg bro

Good Luck to you :) I believe you can do it

Since you are able to reach out to internet, you have great access to various materials on the internet.

Do you have question about C\C++ so ask it. Don't ask question about asking questions.

Just to get things straight... this isn't question... this is a homework assigment

int getPrice(){

AHMED
Why the output of this program is empty?
It should display 766
Alex
what is output? you don`t print anything
AHMED
No output to copy it.

No errors reported

return won't print anything.

You may want to std::cout it.
