plz solve this problem.

For this exercise, we will examine the code generated by GCC for functions that have structures as arguments and return values, and from this see how these language features are typically implemented. The following C code has a function word sum having structures as argument and return values, and a function prod that calls process: 1 typedef struct long a C21; long *p; strA 6 typedef struct f long u [2]; long 9 strB 10 11 str process (strA s) f strB r 12 r. u [0] s. a [1] [11 a [0] r, u 14 *s.p r.q. 15 return r 17 18 19 long eval long x, long y, long z) f strA s 20 s a[01 21 s. a[1] 23 str r process (s) 24
