How many programming language should i learn to be a programmer??

Answer 1

you should be proficient in at least one language.

There is no set number of languages that you should know. Learn programming languages as the need arises. Don’t learn them for the sake of learning. You’d be wasting your time and energy.
If you need to write web apps, consider PHP, Java, Python, Ruby.
If you need to write mobile apps, consider Java/Kotlin and Swift.
If you need to write video games, consider C++ and C#.
If you need to write programs for data science and machine learning, consider Python and R.
If you need to write IoT apps, consider C, Python, and Java.
And so on. Only learn what you need.
