I was wondering why I get a compile error when I try to use std::cout in between, say, an if statement and else if statement.
For example:
if (condition)
{body}
std::cout << "hello world" << std::endl;
else if (condition)
{body}
Gives the error
error: 'else' without a previous 'if'

Answer 1

Let me get this right first:
You want to execute the cout statement in between the conditional no matter whether the condition was met or not, i.e. no matter whether the body of the if got executed or not.
As previous commenters noted, you cannot place something between the end of scope of the if-block and the else keyword.
What about approaching this by splitting up the if-else-if block into two separate if-blocks:
if (condition1) {
body1
}
cout << "hello world" << endl;
if (!condition1 && condition2) {
body2
}

Answer 2

That's why indentation is important
if (condition)
{ body
std::cout << "hello world" << std::endl;
}
else if (condition)
{
body
}
In your code, cout is outsite the if block, so no more else is expected.

Answer 3

You cannot add any executable code between if and else if other than the enclosed body of the if and else if loops.
if (firstCondition)
{
/*code for firstCondition*/
//code anything here
}
//not here #######
else if (secondCondition)
{
/*code for secondCondition*/
//code anything here
}

Answer 4

Correct is:
if (condition)
{
std::cout << "hello world" << std::endl;
}
else if (condition)
{body}

Answer 5

That would be an option for you.
if (fistCondition)
{
/*code for fistCondition*/
std::cout << "hello first" << std::endl;
}
else if (secondCondition)
{
/*code for secondCondition*/
std::cout << "hello second" << std::endl;
}
If you wanna call the cout in any case between the first and second condition, then avoid the else keyword and apply two if statements.
if (fistCondition)
{
/*code for fistCondition*/
std::cout << "hello first" << std::endl;
}
std::cout << "posterior to first and prior to second if statement" << std::endl;
if (secondCondition && !firstCondition)
{
/*code for secondCondition*/
std::cout << "hello second" << std::endl;
}
In this case, && !firstCondition emulates an else keyword for your purpose.
