What are coding languages?

Coding languages are distinct sets of text and characters that, in specific arrangements, produce a desired outcome in a computer program. All software uses a coding language that gives directions to the system. Coding languages are used to create complex algorithms for computer programs. When describing coding languages, developers refer to the language's syntax, or the specific form of the characters, and its semantics, or what the characters means.

Consider the following example in Python language to add two numbers:

num1 = 15

num2 = 12

# Adding two nos

sum = num1 + num2

# printing values

print("Sum of {0} and {1} is {2}" .format(num1, num2, sum))

The output of this code is "Sum of 15 and 12 is 27."
