Answer:
The expression is :
π[cd) + π(g,h) ],[π(e,f)+π(a,b)])
We will use foreign key and primary key
Answer:
The code will display the following on the screen:-
2
0
2
Explanation:
The output is like this because x{2} assigns the value 2 to the integer x.First the value of x is printed on the screen that is 2 and that newline is used to go to the next line.After that function is called doSomething with x passed as the argument. doSomething function assigns the value zero to the variable passed and prints it on the screen.So the next line is 0.Since x is passed by value so no changes will appear in the original argument.Hence the last line printed is 2.
Answer:
The answer is "True".
Explanation:
The web beacons are one of the different techniques, that are used on web pages and emails, to check whether a user has access to some unobtrusively. It is a line, that is often invisible, and typically does not exceed 1 pixel.
- It is usually used with cookies.
- It is also known as a small graph, which generates a request to the server for tracking service.
Here is a somewhat cryptic solution that works:
#include <algorithm>
#include <cstdlib>
using namespace std;
void q(char c, int count)
{
for (int i = 0; i < count; i++) {
putchar(c);
}
}
void p(int b1, int plusses)
{
q(' ', b1);
q('+', plusses);
}
int main()
{
for (int i = -3; i <= 3; i++)
{
int pl = min(6, (3 - abs(i)) * 2 + 1);
p(6-pl, pl);
i == 0 ? p(0, 6) : p(6, 0);
p(0, pl);
putchar('\n');
}
getchar();
}
Whichever action you take to complete a task will inevitably affect the end result of whatever would need to be accomplished; whether this impact the task in a positive or a negative way.
