C语言_结构体变量指针做函数参数的使用案例

# include <stdio.h>
# include <stdlib.h>
# include <string.h>
# include <malloc.h>


//创建一个结构体
typedef struct programmer
{
    int salary;
    int experience;
    char type[15]; 
    
} Programmer;

void OneyearLater(Programmer *);
int main ()
{
    Programmer p = {15000, 3, "PHP"};
    printf("岗位:%s
当前薪资:%-5d
当前经验:%d年
",p.type, p.salary, p.experience);
    OneyearLater(&p);
    printf("------------------一年后---------------------
");
      printf("岗位:%s
当前薪资:%-5d
当前经验:%d年
",p.type, p.salary, p.experience);
       
    return 0;
}
//一年后 
void OneyearLater(Programmer *p)
{
    p->salary = 18000;
    p->experience = 4;
    
}
