‘1’. Each character in the bit-string literal represents one, three or four successive elements of the array value, depending on whether the base specified in the literal is binary, octal or hexadecimal. Again, usingstd_ulogic_vectoras an example type, we can write a constant declaration ...
Strings as inputs: Concatenates multiple strings and returns a new string. Parameters a and b: required. These parameters specify arrays. T in array<T> specifies the data type of the elements in the arrays. The elements can be of any data type. The elements in Array a and the elements...
