Which is the diference between std::cout and cout?? C++ have if and else statement where is else if or if else???

Answer 1

We use if else like below
if(something)
Do that
else
Do that
And we use else if when there is more criteria for example
If (num==x)
do something
Else if (num>x)
do something
Else //this is if num<x
do something

For examle:
Firstly
#include <iostream>
using namespace std;
int main(){
cout<<"Hello world!!!"<<endl;
return 0;
}
Secondly
#include <iostream>
int main(){
std::cout<<"Hello world!!!"<<endl;
