SUMMARY
In Fortran, specifically using the GNU g95 compiler, users can input strings rather than numbers by utilizing the READ statement. The example provided demonstrates how to read a character string into a variable and compare it using the equality operator (==) in Fortran 95. For earlier versions, the comparison operator should be .EQ. instead of ==. This method allows for user-defined string inputs, such as 'exit', to control program flow.
PREREQUISITES
- Understanding of Fortran programming language syntax
- Familiarity with the GNU g95 compiler
