Why the output is 65 explain please.

Question

#include <stdio.h>
#define x 10+5
int main(){
int a=x*x;
printf("%d",a);
return 0;
}
//output is 65.

Answer 1

10+5*10+5

As per basic math rule, first multiplication will happen then addition
10+50+5 = 65

Answer 2

Let's break the code
#define is used to declare any variable with constant values which can not be changed through out the code.
Now a = x*x is 10+5*10+5

As Rishi Anand said according to basic math rules(division, multiplication, addiction, subtraction).
So 10+5*10+5 -> 10+50+5 -> 65.

Answer 3

follow basic math rule,
division, multiplication, addition, subtraction.
10+5*10+5=65.

Answer 4

All the guys before explained the science behind your problem, I'd just add it is considered good practice for your definitions to be clear stated and usually comprised of a single sign avoiding operations and multiple objects😊😊
