Declaration of Computational Arrays Computational arrays are treated as first-class objects in Ch. Computational arrays are declared with the type qualifier array defined in array.h . Programs using computational arrays should include the header file array.h . At the interactive prompt in Ch shell, computational arrays can be used without header file array.h. The code segment below declares computational arrays a1, a2, a3, a4. One-dimensional arrays a1, a2 , and a3 are of int type with ten elements. The subscript ranges of arrays a1 and a2 are from 0 to 9. The subscript range of array a3 is from 1 to 10. Array a4 is a two- dimensional array. #include <array.h> int main() { array int a1[10]; // a1[0], ..., a1[9] array int a2[0:9]; // a2[0], ..., a2[9] array int a3[1:10];// a3[1], ..., a3[10] array double a4[10][10]; /* ... */ }
