c - 使用动态输入时分配的垃圾值；用C语言

Question

问题在于，在输出中，属性 sp、bp、temp、cold、fever 和 stomach 被分配了垃圾值，而且为 symp[i] 输入的字符串没有正确存储。这不是完整的程序，它还有一些补充需要完成。

程序如下..头文件是stdio.h和conio.h

#include<stdio.h>
#include<conio.h>
void main()
{    
 char * symp[10];
 int n=0,i,sp,dp,cold,fever,stomach;    
 float temp;   
 clrscr();
 printf("Enter your body temperature: ");    
 scanf("%f",&temp);    
 printf("Enter your systolic BP: ");    
 scanf("%d",&sp);    
 printf("Enter your diastolic BP: ");    
 scanf("%d",&dp);    
 printf("Enter the no of symptoms: ");    
 scanf("%d",&n);    
 printf("Enter the symptoms you have, one by one\n");
 fever=cold=stomach=0;    
 for(i=0;i<n;i++)    
 {    
  scanf("%s",symp[i]);    
  printf("i=%d\tn=%d\n",i,n);    
  if(symp[i]=="cough")    
  { cold=cold+1;}    
  if(symp[i]=="sneezing")    
  { cold=cold+1;}    
  if(symp[i]=="running_nose")    
  { cold=cold+1;}   
  if(symp[i]=="headache")    
  { cold=cold+1;fever=fever+1;}    
  if(symp[i]=="chill")    
  { fever=fever+1;  }  
  if(symp[i]=="weakness")    
  { fever=fever+1; }   
  if(symp[i]=="stomach_pain")
  { stomach=stomach+1; }   
  if(symp[i]=="diarrhoea")
  { stomach=stomach+1;}    
  if(symp[i]=="vomiting")    
  { stomach=stomach+1;fever=fever+1;}
  if(symp[i]=="throat_pain")   
  { cold=cold+1;}    
  if(symp[i]=="body_pain")
  { fever=fever+1;}
 }
printf("Your temperature is: %f\n",temp);
printf("Your BP is: %d/%d\n",sp,dp);
printf("The symptoms are:\n");
for(i=0;i<n;i++)
 {
 printf("%s\n",symp[i]);
 }
printf("cold: %d\nfever: %d\nstomach: %d",cold,fever,stomach);
getch();
}

你不能将 char[] 与 == 的静态字符串进行比较，你必须使用 strcmp 或 strncmp，类似于:

 if (strcmp(symp[i], "headache"))

您还必须将一个地址传递给scanf("%s", ...)，例如:

scanf("%s", &symp[i]);
