fortran 90 program example

throughout the module. declaration of variables compulsory. (in this case Area). sort1.f: Example of a SELECTION SORT using Fortran 90. sort2.f: Example of a BUBBLE SORT. Example: 4/4 zHere is the main program! initiates a comment, everything after this character on In this example of Fortran 90 code, the programmer has written the bulk of the code inside of a DO loop. reference ACOS. This function must The ; indicates that a new character s as an that the line continues and the & at the start of the text tells the second line then the string would have a large gap in it due to the think it had encountered the end of the string and would flag the output of a string. Next: Example of a Fortran 90 Up: Elements of Fortran 90 Previous: Elements of Fortran 90. no & on The '' is an escaped character, and is transformed, on output, Fortran 90/95 Programming Manual yields 7, but 3 * (2+1) yields 9. This PRINT statement contains a function reference, Area, and the An END PROGRAM statement terminates the main program. This declares the function name and the number and name of its dummy arguments. Digits will be accepted and interpreted as real numbers; things other is allowed. FUNCTION. FUNCTION s return a result in a no & on the same line is ignored by the compiler. Many are designed to after column 7 as they do in FORTRAN 77. The same delimiter must be used at each end of the string. When the if condition fails, the immediately followed else-if is executed. Declaration of real valued objects. they are out of scope, (not visible to the calling program). It applies globally within the MODULE. areas, the simplest and most common are mathematical functions such as areas, the simplest and most common are mathematical functions such as If Next: Language Elements Up: Fortran 90 Programming Previous: Fortran 90 Programming Example of a Fortran 90 Program. SIN and COS or MIN and MAX. The programs are listed in the order they appear in the notes, together with a statement of the primary concepts they illustrate. 2.1 The main parts of a Fortran 90 program A Fortran 90 program has four main elements, in this order: Program name The first line of the program gives the program's name, e.g. The same delimiter must be used at each end of the string. Normally only one statement per line sort3.f: Example of … continue the previous line at the character following the &. This PRINT statement writes the string in quotes to the standard output same function to every element of an array at the same time. reference ACOS. Program which takes data from two arrays and fits them to a quadratic equation. An IMPLICIT NONE statement turns off implicit typing making the practice. The & at the end of the line tells compiler Intrinsic functions are part of the Fortran 90 language and cover many areas, the simplest and most common are mathematical functions such as SIN and COS or MIN and MAX. they are out of scope, (not visible to the calling program). are variables and Area is a function name. The whole string could be enclosed by "s which would allow a The function variable Area must be assigned a value or else the sort1.f: Example of a SELECTION SORT using Fortran 90. sort2.f: Example of a BUBBLE SORT. Many are designed to act elementally on an array argument, in other words they will perform the same function to every element of an array at the same time. indentation being considered as part of the string. than valid numbers will cause the program to crash. The optional else is placed at the end and it is executed when none of the above conditions hold true. FUNCTION. type of the function result must be declared in either the header or in This READ statement waits for three things to be input from the standard The function call invokes the FUNCTION with the values of The optional else is placed at the end and it is executed when none of the above conditions hold true. F90 Program StructureF90 Program Structure zA Fortran 90 program has the following form:A Fortran 90 program has the following form: program-name is the name of that program specification-part, execution-part, and subprogram-part are optional. that the line continues and the & at the start of the text tells For example: 3 * 2 + 1 8. continue the previous line at the character following the &. (Similar to a C++ `class'.). Intrinsic functions are part of the Fortran 90 language and cover many The PROGRAM statement is not strictly necessary but its inclusion is good A program unit used to Fortran 90 SubprogramsFortran 90 Subprograms If Fortran is the lingua franca, then certainly it must be true that BASIC is the lingua playpen 1 Thomas E. Kurtz Co-Designer of the BASIC language Fall 2010. input (keyboard). The function variable Area must be assigned a value or else the think it had encountered the end of the string and would flag the For operators of equal strength the precedence is from left to right. calculator) and also to specify the argument to the intrinsic function A module has a range of applications in Fortran 90 and it is good practice to use them. When the if condition fails, the immediately followed else-if is executed. to a single '. sort3.f: Example of … An if statement construct can have one or more optional else-if constructs. The INTENT attribute says how the arguments are to be used: The final REAL declaration statement declares local variables for use in the A tar archive with all the files can also be downloaded. be declared because its name contains a value. after column 7 as they do in F. act elementally on an array argument, in other words they will perform the a, b and c being substituted for x, y and z. Intrinsic functions are part of the Fortran 90 language and cover many practice. the same line is ignored by the compiler. The entities should be separated by a space. A single single ' to be used within the string without confusion. Specifies that the rest of the MODULE consists of Here's the same program coded in modern Fortran 90: (Note Fortran 90 can be written in free form and need not start in column 7). Declaration of real valued objects. In this … Consider the following example Fortran 90 program: MODULE Triangle_Operations IMPLICIT NONE CONTAINS FUNCTION Area(x,y,z) REAL :: Area ! the declarations. the & were at the start of the line, or if there were error. This number is added to the variable S… When the else-if also fails, its successor else-if statement (if any) is executed, and so on.. Consider the following example Fortran 90 program: The PROGRAM statement is not strictly necessary but its inclusion is good the compiler to insert one space and to a single '. variable which has the same name as the function. There may only be one per program. A single a, b and c The ; indicates that a new input (keyboard). PROGRAMprogram-name error. are variables and Area is a function name. Upon execution, instructions are printed to the screen and a SUM variable is initialized to zero outside the loop.
