用變量a給出下面的定義 a)一個(gè)整型數(shù)(An integer) b)一個(gè)指向整型數(shù)的指針(A pointer to an integer) c)一個(gè)指向指針的的指針,它指向的指針是指向一個(gè)整型數(shù)(A pointer to a pointer to an integer) d)一個(gè)有10個(gè)整型數(shù)的數(shù)組(An array of 10 integers) e)一個(gè)有10個(gè)指針的數(shù)組,該指針是指向一個(gè)整型數(shù)的(An array of 10 pointers to integers) f) 一個(gè)指向有10個(gè)整型數(shù)數(shù)組的指針(A pointer to an array of 10 integers) g)一個(gè)指向函數(shù)的指針,該函數(shù)有一個(gè)整型參數(shù)并返回一個(gè)整型數(shù)(A pointer to a function that takes an integer as an argument and returns an integer) h)一個(gè)有10個(gè)指針的數(shù)組,該指針指向一個(gè)函數(shù),該函數(shù)有一個(gè)整型參數(shù)并返回一個(gè)整型數(shù)( An array of ten pointers to functions that take an integer argument and return an integer )
