求帮该代码，结果不对

#include"stdio.h"
main()
{
double basis=0;                          //绩效工资
double post=0;                             //岗位工资
double Overtime=0;                         //加班工资
double piece=0;                             //计件工资
double allowance=0;                        //津贴工资
double Gross_wage=0;                    //总工资     
double standards=800.0;
int a,c;
char b[10];    
double days;
double Par;
printf("请输入员工的个人信息:\n");
scanf("%d",&a);
scanf("%s",b);
scanf("%d",&c);
printf("%d   %s   %d\n",a,b,c);
printf("请输入员工的考勤信息:\n");
scanf("%ld",&days);
printf("请输入员工的表现信息:\n");
scanf("%ld",&Par);
basis=300.0*Par;
{    
    int s,p;
    printf("请输入员工的岗位信息1-4:\n");
    scanf("%d",&p);
    printf("请输入员工的岗位级别1-10:\n");
    scanf("%d",&s);
    if(p==1)          post=500.0*s;
    else if(p==2)  post=300.0*s;
    else if(p==3)  post=150.0*s;
    else if(p==4)  post=100.0*s;
    printf("岗位工资:%d\n",post);
}   
Overtime=(standards/26.0)*days;

{
    int j;
    printf("请输入员工的计件信息:\n");
    scanf("%ld",&j);
    piece=piece+j;                                        //计件工资
}

    allowance=(100.0/26.0)*days;                          //津贴工资

    Gross_wage=allowance+basis+post+Overtime+piece+standards;
printf("员工工资表:%ld  %ld  %ld  %ld  %ld\n",basis,Overtime,piece,piece,allowance);
printf("总工资:%ld\n",Gross_wage);
    
}

我猜 你要实现这个

#define _CRT_SECURE_NO_WARNINGS
#include <stdio.h>

double getPost(double post) 
{
        int s, p;
        printf("请输入员工的岗位信息1-4:\n");
        scanf("%d", &p);
        printf("请输入员工的岗位级别1-10:\n");
        scanf("%d", &s);
        if (p == 1)          post = 500.0 * s;
        else if (p == 2)  post = 300.0 * s;
        else if (p == 3)  post = 150.0 * s;
        else if (p == 4)  post = 100.0 * s;
        printf("岗位工资:%lf\n", post);
        return post;
}
double getPiece(double piece)
{
        double j;
        printf("请输入员工的计件信息:\n");
        scanf("%lf", &j);
        piece = piece + j;                    //计件工资
        return  piece;      
}
int main()
{
    double basis = 0;                          //绩效工资
    double post =0 ;                             //岗位工资
    double Overtime = 0;                         //加班工资
    double piece = 0;                             //计件工资
    double allowance = 0;                        //津贴工资
    double Gross_wage = 0;                    //总工资     
    double standards = 800.0;
    int a, c;
    char b[10];
    double days;
    double Par;
    printf("请输入员工的个人信息:\n");
    scanf("%d%s%d", &a,b,&c);
    printf("%d   %s   %d\n", a, b, c);
    printf("请输入员工的考勤信息:\n");
    scanf("%lf", &days);
    printf("请输入员工的表现信息:\n");
    scanf("%lf", &Par);
    basis = 300.0 * Par;
    post=getPost(post);
    Overtime = (standards / 26.0) * days;
    piece=getPiece(piece);
    allowance = (100.0 / 26.0) * days;                          //津贴工资
    Gross_wage = allowance + basis + post + Overtime + piece + standards;
    printf("员工工资表:%lf  %lf  %lf  %lf  %lf\n", basis,post,Overtime, piece, allowance);
    printf("总工资:%lf\n", Gross_wage);

    return 0;
}

scanf语法不对，应该是%lf

%ld改成%lf吧，变量都是double
