Match the items of List-I in C++ with the items of List-II in FORTRAN : Codes :List - I List - II a. Global variables i. Computed GOTO b. Static ii. EQUIVALENCE c. Reference iii. COMMON d. Switch iv. SAVE
a-iii, b-iv, c-ii, d-i
To match the items correctly between C++ and FORTRAN, let's understand the equivalents of each item:
- Global Variables (C++): In C++, global variables are those that can be accessed by any function in the program. The equivalent concept in FORTRAN is the COMMON block, which allows sharing variables among different program units.
- Static (C++): In C++, the
statickeyword is used to preserve the value of a variable between function calls. The equivalent in FORTRAN is the SAVE attribute, which retains the values of variables across invocations. - Reference (C++): References in C++ provide an alias for another variable, allowing it to be accessed using a different name. FORTRAN uses the EQUIVALENCE statement to achieve a similar behavior by associating multiple names with the same memory location.
- Switch (C++): The
switchstatement in C++ is used for multi-way branching based on the value of a variable. The FORTRAN equivalent of this is the Computed GOTO, which allows branching to different parts of the code based on a computed value.
Based on this understanding, the correct matching is:
| List - I | List - II |
| a. Global variables | iii. COMMON |
| b. Static | iv. SAVE |
| c. Reference | ii. EQUIVALENCE |
| d. Switch | i. Computed GOTO |
Thus, the correct answer is a-iii, b-iv, c-ii, d-i.
