Little C

This is the Think C 6.01 version of Little_C -- a subset C interpreter by Herbert Schildt. Little C is a C interpreter that can execute a subset of K&R ANSI C programming language. ANSI C is a robust and powerful programming language, but the Little C interpreter only implements a limited range of features. These include: parameterized functions with local variables; recursion; if statement; do-while, while, and for loops; integer and character variables; global variables; integer, character, and string constraints; return statement; several library functions; several operators; functions returning integers; and comments. A recursive-descent parser is used to implement the C interpreter. Details of the development, coding, and functionality of the C interpreter are described in Schildt, Herbert. Building your own C interpreter. Dr. Dobb's Journal of Software Tools v14, n8 (August, 1989):38 (16 pages).
