I did not get what is the use of using namespace std and can we use codeblocks instead of sublime as i am unable to install g++ compiler and can you tell why do we write return 0;
C++ code unable to understand and not able to download the compiler
Hey @jhaisha0003
In each scope, a name can only represent one entity. So, there cannot be two variables with the same name in the same scope. Using namespaces, we can create two variables or member functions having the same name.
Yes you can used codeblocks instead of sublime text
When you declare your int main () {
Function
At the end of it always write
Return 0
}
If you still have any doubt you can ask for it
