18SPR-ENCE2303-001 Program Graphics Lab Programming Assignment 6: Soil Classification Title: SoilClassificationSubroutine (.f9o, exe, and soil.dat) Instructions: Unified Soil Classification Systenm (4pts)Write a Fortran 9o program that uses the Unified Classification System (figure provided in class)to classify coarse grained soils. (apts)The user must have the choice of entering data on screen or reading the data from a file named "soil.dat" in the order shown in the example. You will need to create a "soil.dat" file with the numbers listed in it with no formatting. This "soil.dat" file can be saved in the same location as the .fgo file. Be sure to save as .dat and NOT.txt. 2pts)The program must contain a minimum of two subroutines. Submit the name.f9o, name.exe, and soil.dat files to the Assignments box. (2 pts) Turn your pseudocode or flowchart during class. TEST DATA to get dual classification of SP SC Percent Passing No.4 sieve: 100 Percent Passing No.20o sieve: 8 18SPR-ENCE2303-001 Program Graphics Lab Programming Assignment 6: Soil Classification Title: SoilClassificationSubroutine (.f9o, exe, and soil.dat) Instructions: Unified Soil Classification Systenm (4pts)Write a Fortran 9o program that uses the Unified Classification System (figure provided in class)to classify coarse grained soils.
