在给结构体成员赋值的时候，函数参数只能使用指针么？

Question

我尝试不用指针，用结构类型变量作为函数参数，就是修改的图中的fill函数的参数，结果报错说 主函数定义的结构体变量（即c）未初始化

Answer 1

#include #include using namespace std;const int seasons = 4;const char* sname[seasons] = {"Spring","Summer","Fall","Winter"};struct cash{ double pa[seasons];};void fill(cash* a);void show(cash b);int main(){ cash c ; fill(&c); show(c); system("pause"); return 0;}void fill(cash* a){ for(int i=0;i> a->pa[i]; }}void show(cash b){ double total=0.0; cout << "\nEXPENSES\n"; for(int i=0;i < seasons;i++) { cout << sname[i] << ": $" << b.pa[i] << endl; total +=b.pa[i]; } cout << "Total Expenses: $" << total << endl;}
