#include int main(void) { Int x, y, sum; printf(“Enter two numbers: ); scanf(“%d%d”, &x, &y); sum = x+y; printf(sum); Or, forgo sum altogether and printf(x + y); return 0; }
What about if you want the user to be able to enter more numbers for the sum without knowing how many numbers he will enter? Asking because that’s my homework for this week. Trying to figure out how to write a program for multiple numbers where as it outputs sum of even numbers, sum for odd numbers, and total sum.
Use the "for" loop. int n, x, s=0; cin >> n; for(int i=1; i> x; // this will be read n times s = s + x; // adds the current number to the sum } Let's say you have 4 numbers (3 7 9 18). i (from the for loop) will start out as 1, it will check if it's smaller then n (which in this case will be 4, cause we have 4 numbers) then it will execute what's inside the for loop. Then i will increase and so on. I'm guessing you know how to check if a number is odd or even using if statements.

I don’t think “using namespace std” is a healthy convention. In a larger codebase, you might accidentally overwrite one of the std functions if someone unknowingly writes a function with the same function name as a common std function
Using namespace std, declaring all your variables at the top of a scope block, and using a comma to declare multiple things on one line are all horrible practices in C++.
In C this program looks like this: #include int main() { int a, b, sum; printf("Enter two numbers: "); scanf("%d%d", &a, &b); sum = a + b; printf("a + b = %d", sum); return 0; }

C :
#include
int main() {
int x = 5;
int y = 6;
int sum = x + y;
printf("%d, sum);
return 0;
}
Output : 11
#include
int main(void) {
Int x, y, sum;
printf(“Enter two numbers: );
scanf(“%d%d”, &x, &y);
sum = x+y;
printf(sum);
Or, forgo sum altogether and
printf(x + y);
return 0;
}
Very help . For you thank you
How can I get 30s of my life back. Do it using pointers.
Very helpful.. thank you so much 🙏
You should use
export inline template requires (Ty1 obj1, Ty2 obj2) { obj1 + obj2; } auto get_sum(const Ty1& obj1, const Ty2& obj2)->decltype(obj1 + obj2)noexcept(noexcept(obj1 + obj2)){
return obj1 + obj2;
}
Not really.
Try hard
True
or just use double datatype
Why? If he wants to add two integers, then he will add two integers, no need for templates. Don't complicate things.
Fun to code
Use correct initialization int a{}, etc.
Y bhtt intrsting h yrr m to ab shuru krri hu seekhna i am b com krliya h ab complete but man h to bs seekhna h ye bhi i hope easy rho
all the best! it's always good to see a non-techy trying coding
I was always doing cout no. 1;
And then repeat with no. 2 but i see that i can just do cin >> a >> b;
Very easy
Thanks

the horizontal and vertical whitespacing in this code is making me have a conniption
Lol, std::cout instead of using namespace std😅
It's not funny. Both are correct.
@@toby9999 For a beginner programmer, yes, but in real projects, using namespace std can consume memory.
@@Merovingien514consume memory? I don't think so.

I would genuinely rather walk on burning coal than code on mobile, no offense
in cout, remove the quotes where a+b so the numbers that you entered instead of letters will be output
But you can make it with "switch" and "case" or also "if" and "else"
Isnt that Python?

Using namespace std, declaring all your variables at the top of a scope block, and using a comma to declare multiple things on one line are all horrible practices in C++.
Says who? You?
Why? xD
Using namespace std is fine for such simple programs. Multiple declarations separated by comma is also fine, it's valid syntax.
Wrong this code 😢
