What is the value of the redundant return statement inside the braces?
One of my first jobs was processing in a 16K space, and the data was 12K per record. We coded very concisely as we had no room for extraneous code. Today's compilers are far more efficient, but making the processing straightforward and eliminating redundant code is still a good idea.
Yeah, the lack of ability in some cases is amazing, and not in a good way.
My boss tells a story of a former employee who made cut-n-paste an art form. Modern art form. This person appears to have never written a line of code -- everything was copied from other programs and web sites, and this person could not understand why the program would not work.
In another situation I taught a COBOL programmer with 5 years experience how to program. I am not a COBOL programmer and have never compiled a single line. This is not picking on COBOL -- this guy did not understand program flow. OTOH, he was fantastic at phone support, which is where he should have been.
My first developer job at Microsoft required me to analyze code written by a 'developer who got promoted so is no longer available. I and another dev spent hours analyzing this C language mess. Finally, after hours of analysis, we traced deep enough to get to the root of what the code was doing. Result? It returned the number 1.
Yup, that is all the entire 20K lines of code did. The reason it never worked? The array this was used to dereference only had 1 element.
What's wrong with returning from inside an if? The rule about only returning at the end of a function leads to convoluted code where a flag is repeatedly used to bypass stuff just to reach the end of the function. Pure dross.
It's quite clear, right in the return statement. If the only return is at the end of the function, you have to find all the places that can set the returned value, and figure out whether that value survives to the end of the function or gets updated.
If the return is within an "check initialized stuff" at the beginning... nothing.
If there are 3 or more returns... it might get so confusing / convoluted as having only one at the end.
If something has a solution... Why do we have to worry about?. If it has no solution... For what reason do we have to worry about?

Rating helpful answers is nice, but saying thanks can be even nicer.
If you have allocated anything that is not an automatic object that can be risky.
I have dealt with a few customers who had explicit code-style prohibitions against multiple return statements. Given the rest of the nonsense we had to deal with from them that was pretty much ignored. I hated those SFBs so much I refuse to buy any of their products ever again. To give a clue, they used to be referred to as a purveyor of expensive ink.
