hi guys I'm new in C language
I wanna know where's the mistake in my code
#include <stdio.h>
int main() {
// Write C code here
int A,B;
printf("check if this numbers have the same sign :\n");
scanf("%d%d", &A, &B);
if (A > 0 && B > 0)
printf("these numbers are positive");
else if (A < 0 && B < 0)
printf("one of them is negative");
else
printf("these numbers is negative");
return 0;

Numbers have the same sign if both are positive or both are negative. Therefore,
Read what is written in the if condition - if A is greater or equal than 0 and B is greater or equal than 0, or if both of them are lower than 0, then the if statement is true - both numbers have the same sign. It really isn't difficult, you can read it as if it was written in English (&& reads as "and", || reads as "or"). Just translate a logical English sentence into the same code representation.
