Explanation:
Three address statements are used in computer programming languages to represent the intermediate code generated during compilation or interpretation. They are called three address statements because they typically have three operands or addresses: one for the result and two for the operands. These statements are used to represent simple operations such as arithmetic calculations, assignments, and control flow statements.
Types of Three Address Statements:
1. Copy statements: Copy statements are used to assign the value of one variable to another variable. For example, if we have two variables A and B, the copy statement would be "B = A".
2. Index assignment statements: Index assignment statements are used to assign a value to an element of an array or a data structure that can be indexed. For example, if we have an array A and we want to assign a value to its element at index i, the index assignment statement would be "A[i] = value".
3. Pointer assignments: Pointer assignments are used to assign a memory address to a pointer variable. Pointers are variables that store the memory address of another variable. For example, if we have a pointer variable P and we want to assign the memory address of a variable X to P, the pointer assignment statement would be "P = &X".
Answer:
The correct answer is option 'D' (None of the above). This means that all the given options (copy statements, index assignment statements, and pointer assignments) are types of three address statements. Therefore, none of the options is not a type of three address statements.
