If a=10, a++=11

Question

Need explaination in detail

Answer 1

What do you need help with? The syntax or the comparison

Answer 2

There’s nothing to solve, what you have stated is what would happen.

If a equals 10.

Then a (after, as using postfix increment) equals 11.

Answer 3

a = 10, a++ is also 10 not 11 but after a++ , a is 11

Try this:

#include <iostream>
using namespace std;

int main() {
int a = 10;

cout << a++ << endl;
cout << a;
return 0;
}

if there is pre-increment like ++a then ++a is 11, and after ++a, a will also be 11

Try this:

#include <iostream>
using namespace std;

int main() {
int a = 10;

cout << ++a << endl;
cout << a;
return 0;
}

Please don't put tags like Pakistan

Answer 5

Bro I am just having problem due to ++ what is the value or mean of plus here so

Answer 6

Arham Fayyaz

It just simply adds the value by 1

Answer 7

Arham Fayyaz
Explain what problem you are having. I have suggest possible fixes (where not using equality operator) and explained the postfix increment is increasing the value by 1.

Here is a working example:

#include <iostream>

int main() {
int a {10};

if (a == 10)
a++;

std::cout << a;

return 0;
}

Answer 8

I think what he needs is just an explanation of what ++ does according to his question and comment 🤔

Answer 9

Firstly you are using an assignment operator in a comparison statement.

You would use == to check equality.

Secondly you don’t assign an increment operator a value.
a++ is the same as a += 1 (or a = a + 1) and doesn’t require an assignment value.

Here’s an example:

If (a == 10):
a++

( a now equals 11)

Answer 10

Can you solve?
