In computer science, manifest typing is when the software programmer explicitly identifies the type of each variable being declared. For example: if variable X is going to store integers then its type must be declared as integer.
Type inference, or implicit typing, refers to the ability to deduce automatically the type of a value in a programming language. It is a feature present in some strongly-typed programming language static typing#Static and dynamic typing languages.... (aka. type inference) where the type is deduced from context or allow for dynamic typing
Type system
In computer science, a type system may be defined as "a tractable syntactic method for proving the absence of certain program behaviors by classifying phrases according to the kinds of values they compute.".... in which the variable is just declared and may be assigned a value of any type at runtime.

Note that the variables s, x, and y were declared as a character array, floating point number, and an integer respectively. The type system rejects, at compile-time, such fallacies as trying to add s and x.
Standard ML is a general-purpose, Module , functional programming language with compile-time type checking and type inference. It is popular among compiler writers and programming language researchers, as well as in the development of automated theorem proving.... , the types are not explicitly declared. Instead, the type is determined by the type of the assigned expression.
There are no manifest types in this program, but the compiler still infers the types string, real and int for them, and would reject the expression s+x as a compile-time error.
