Which of the following are roles the president carries out under the constitution and tradition?

The first role is the Head Of state
This role enables the president to create the government and choose the secretaries who run various departments found in the United States, for example, the State department or the Department of Defense or anything similar. The president chooses who these people would be and the congress approves of this.

The second is the Chief Diplomat
This role means that the president is in charge of negotiating treaties and deals with other countries, whether it be trade deals or peace talks or similar things. When a president makes a treaty or a deal, the congress chooses whether to ratify it after which it becomes a legitimate treaty that is supported by the US.
The third is the Chief Executive

This role makes the president the chief of the executive branch. This means that the president is ideally in charge of things like the police or the various other executive agencies. He can also sign executive orders which are like laws that are quickly implemented and they go through the supreme court's examination for constitutionality.
The fourth is the Commander in Chief
This means that the president is also the highest ranking military officer of the entire army, including navy, airforce, and all similar types of armies. The president participates with generals in making policies or plans and gets reports from battlefields and similar things and basically controls all things related to the military.
The fifth is the Chief Legislator
The president and his cabinet make laws that are then either adopted by the congress or are disposed. The president also has a huge role in influencing the fate of laws that are made by non-president parties such as various groups since usually the support of the president for a law means that there is a higher chance that it will get passed.
