编写C语言程序实现对产品信息管理

#include <stdio.h>

struct chanp

{

int chan_ID

char chan_Name[20]

float chan_Price

}

struct chanp chanp1[3] = {{1001,"Asdf",100.2},{1002,"Bsdf",123.3},{1003,"Cfd",3313.0}}

void main()

{

struct chanp* p

printf("Information: 产品编号 产品名称 产品价格\n")

for(p=chanp1p<chanp1+3p++)

{

printf("%d%10s%15.2f\n",p->chan_ID,p->chan_Name,p->chan_Price)

}

终于结束了

新鲜出炉，还有些BUG，缺和粗可以自行修改。

#include<stdio.h>

int main()

{

double rental//rental销售总额

double pri[5]={2.46,4.95,9.12,4.35,6.66}//pri[]零售价格

int i,num[5],count[5]//num[]名字棚链,sale[]销售数伏镇量

for (i=1i<6i++)

{

printf ("输入第%d种商品名字和销售量:\n",i)

scanf ("%d %d",&num[i],&count[i])//无法限制用户输入数据类型，可产生bug

printf ("商品名字:%d,价格:%f,销售量:%d\n",num[i],pri[i],count[i])//可注释

rental += pri[i]*count[i]//+=

}

printf ("销售总额是%f\n",rental)

}
